Dealing with dates and times in Python can be a hassle. Thankfully, there is a build - in way of making it easier: Python datetime module. Datetime helps us identify and process time - related elements like dates, hours, minutes, seconds, days of week, months, years, etc. It offers various services like managing time zones and daylight savings time. It can work with timestamp data. It can extract day of week, day of month, and other date and time formats from strings. In short, it is a really powerful way of handling anything date and time related in Python. So let's get into it! In this tutorial, you learn about Python datetime functions in detail, including: creating Date Objects Getting years and months from Date Getting months, days and Weekdays from Date Getting hours and minutes from Date Getting Weeks number of year from Date Converting Date object into timestamp Converting UNIX timestamp string to Date object Handling timedelta Objects Getting difference between two dates and times Formatting dates: strftime and strptime Handling timezones Working with Pandas datetime Objects Getting year, month, day, hour, and minute Getting Weekday and day of year Converting Date Objects into DataFrame index as you work through this tutorial, wed encourage you to run code on your own machine. Alternatively, if you like to run code in your browser and learn in an interactive fashion with answer - checking to be sure you are getting it right, our Python intermediate course has lessons on datetime in Python that we recommend. You can start learning by signing up for a free user account. We can see from the results above that datetime_object is indeed datetime object of datetime class. This includes year, month, day, hour, minute, second, and microsecond. Note that strptime takes two arguments: string and% y -% m -% d, another string that tells strptime how to interpret input string my_string.% Y, for example, tell it to expect the first four characters of string to be year. A full list of these patterns is available in the documentation, and well go into these methods in more depth later in this tutorial. You may also have noticed that time of 00: 00: 00pm has been added to the date. That is because we create a datetime object, which must include date and time. 00: 00: 00 is the default time that will be assigned if no time is designated in string were inputting. Anyway, we were hoping to separate out specific elements of date for our analysis. One way can do that is using built - in class attributes of datetime object, like. Month or. Year: now we can see that Python starts weeks on Monday and counts from index 0 rather than starting at 1. So it makes sense that number 3 is converted to Thursday as we saw above. Note that in the ISO calendar, week starts counting from 1, so here 5 represent the correct day of week: Friday.

Get Current Timestamp using time.ctime()

There are multiple ways you can convert timestamp to human readable form in Python. For this conversion you may either use module datetime or time. Module datetime provides classes for manipulating date and time in a more object - oriented way. Import datetime readable = datetime. Datetime. Fromtimestamp.

Python Time as an Object #

When youre working with date and time related strings, it can be very valuable to convert timestamp to time object. To convert Time string to struct_time, you use strptime, which stands for string parse Time: first argument to strptime must be the timestamp you wish to convert. The second argument is the format that timestamp is in. Format parameters are optional and default to% b% d% H:% M:% S% Y. Therefore, if you have a timestamp in that format, you do need to pass it as an argument: since struct_time has 9 key dates and time components, strptime must provide reasonable defaults for values for those components it ca parse from string. In previous examples, tm_isdst = - 1. This means that strptime cant determine by timestamp whether it represents daylight savings time or not. Now you know how to work with Python times and dates using the Time module in a variety of ways. However, there are other uses for time outside of simply creating time objects, getting Python Time strings, and using seconds elapse since epoch.

Stop using utcnow and utcfromtimestamp

Python datetime instances support several types of arithmetic. As you saw earlier, this relies on using timedelta instances to represent time intervals. Timedelta is very useful because it is built into the Python Standard library. Here is an example of how to work with timedelta: in this code, you create now, which stores the current time, and tomorrow, which is timedelta of + 1 day Next, you add now and tomorrow to produce datetime instance one day in the future. Note that working with naive datetime instances, as you are here, means that day attribute of datetime increments by one and does not account for any repeated or skipped time intervals. Timedelta instances also support negative values as input to arguments: in this example, you provide - 1 as input to timedelta, so when you add now and yesterday, result is decreased by one in days attribute. Timedelta instances support addition and subtraction as well as positive and negative integers for all arguments. You can even provide a mix of positive and negative arguments. For instance, you might want to add three days and subtract four hours: in this example, you add three days and subtract four hours, so the new time is on January 29 at 5: 37 AM. Timedelta is very useful in this way, but it is somewhat limited because it cannot add or subtract intervals larger than day, such as month or year. Fortunately, dateutil provides a more powerful replacement called relativedelta. The basic syntax of relativedelta is very similar to timedelta. You can provide keyword arguments that produce changes of any number of years, months, days, hours, seconds, or microseconds. You can reproduce the first timedelta example with this code: in this example, you use relativedelta instead of timedelta to find datetime corresponding to tomorrow. Now you can try adding five years, one month, and three days to now while subtracting four hours and thirty minutes: notice in this example that the date ends up as March 1 2025. This is because adding three days to now would be January 29, and adding one month to that would be February 29, which only exists in leap year. Since 2025 is not leap year, date rolls over to next month. You can also use relativedelta to calculate the difference between two datetime instances. Earlier, you used subtraction operator to find the difference between two Python datetime instances, PYCON_DATE and now. With relativedelta, instead of using subtraction operator, you need to pass two datetime instances as arguments: in this example, you create a new datetime instance for tomorrow by incrementing days field by one. Then, you use relativedelta and pass now and tomorrow as two arguments. Dateutil then takes the difference between these two datetime instances and returns the result as relativedelta instance. In this case, difference is - 1 day since now happen before tomorrow. Dateutil. Relativedelta objects have countless other uses.


Creating Python datetime Instances #

Python datetime instances support two types of operation, naive and aware. The basic difference between them is that naive instances do contain time zone information, whereas aware instances do. More formally, to quote Python documentation: this is an important distinction for working with Python datetime. Aware datetime instance can compare itself unambiguously to other aware datetime instances and will always return correct time interval when used in arithmetic operations. Naive datetime instances, on other hand, may be ambiguous. One example of this ambiguity relates to daylight saving time. Areas that practice daylight saving time turn clocks forward one hour in spring and backward one hour in fall. This typically happens at 2: 00 AM local time. In spring, hours from 2: 00 AM to 2: 59 AM never happen, and in fall, hours from 1: 00 AM to 1: 59 AM happen twice! Practically, what happens is that offset from UTC in these time zones changes throughout the year. Iana tracks these changes and catalogs them in different database files that your computer has installed. Using a library like dateutil, which uses IANA database under hood, is a great way to make sure that your code properly handles arithmetic with time. This doesnt mean that you always need to be aware of datetime instances. But aware instances are crucial if youre comparing times with each other, especially if youre comparing times in different parts of the world.


Starting Your PyCon Countdown #

Earlier, you learn about creating datetime instances Strptime. This method uses special mini - language within Python to specify how date string is format. Python datetime has additional method call. Strftime that allows you to format datetime instance into string. In a sense, it reverse operation of parsing Strptime. You can differentiate between two methods by remembering that p in. Strptime stands for parse, and f in. Strftime stands for format. In your PyCon countdown, you can use. Strftime to print output to let user know the date on which PyCon US will start. Remember, you can find formatting codes that you want to use on strftime. Org. Now add this code on line 18 of your PyCon countdown script: in this code, line 18 is uses. Strftime to create string representing the starting date of PyCon US 2021. Output includes weekday, month, day, year, hour, minute, AM or PM, and time zone: on line 19, you print this string for users to see with some explanatory text. The last line prints the amount of time remaining until PyCon start date. Next, youll finish your script to make it easier for other people to reuse.

Naive datetimes as local time

Aware datetime object embed timezone information. Rules of thumb for timezone in Python: always work with offset - aware datetime objects. Always store datetime in UTC and do timezone conversion only when interacting with users. Always use ISO 8601 as the input and output string format. There are two useful methods: pytz. Utc. Localize to convert naive datetime to timezone be offset - aware, and aware_dt. Astimezonepytz. Timezone for adjusting timezones of offset - aware objects. You should avoid naive_dt. Astimezone, which would converted to aware datetime as system timezone then converted to some_tzinfo timezone. For working with PYTZ, it is recommended to call Tz. Localize instead of naive_dt. Replace. Dt. Replace do not handle daylight savings time correctly.

Conclusions

Historical Context: If youre interested in why timegm is not in time, you can view the discussion in Python Issue 6280. In short, it was originally Add to the calendar because Time closely follows Cs Time library, which contains no matching function. The above - mentioned issues propose the idea of moving or copying timegm into time. However, with advances in Datetime library, inconsistencies in patched implementation of Time. Timegm, and question of how to handle calendar. Timegm, maintainers decline patch, encouraging use of Datetime instead. Further Reading: While representing Dates using Python Time is completely valid and acceptable, you should also consider using the Python Datetime Module, which provides shortcuts and a more robust framework for working with Dates and times together. For example, you can simplify outputting Date in ISO 8601 format Using Datetime: To learn more about Using Python Datetime Module, check out Using Python Datetime to Work With Dates and Times


Creating Python datetime Instances #

Another way to create date instances is to use. Them Fromisoformat. To use this method, you provide string with date in ISO 8601 format that you learned about earlier. For instance, you might provide a string with year, month, and date specify: This string represents the date January 31 2020, according to ISO 8601 format. You can create a date instance with the following example: in this code, you use date. Fromisoformat to create a date, for instance for January 31 2020. This method is very useful because it based on the ISO 8601 standard. But what if you have string that represents date and time but isnt in ISO 8601 format? Fortunately, Python datetime provides method call. Strptime to handle this situation. This method uses special mini - language to tell Python which parts of string are associated with datetime attributes. To construct datetime from string Strptime, you have to tell Python what each of the parts of string represents using formatting codes from mini - language. You can try this example to see how. Strptime works: on line 1, you create a date_string, which represents the date and time January 31 2020, at 2: 45: 37 PM. On line 2, you create format_string, which uses mini - language to specify how parts of date_string will be turned into datetime attributes. In format_string, you include several formatting codes and all of the dashes, colons, and spaces exactly as they appear in date_string. To process date and time in date_string, you include the following formatting codes: complete listing of all of the options in mini - language is outside the scope of this tutorial, but you can find several good references on the web, including in Python documentation and on a website called strftime. Org. Now that date_string and format_string are define, you can use them to create datetime instance. Here is an example of how. Strptime works: in this code, you import datetime on line 3 and use datetime. Strptime with date_string and format_string on line 4. Finally, line 5 shows values of attributes in datetime instance created by. Strptime. You can see that they match values shown in the table above.


Python Time as an Object #

Epoch uses UTC for its definition rather than Time zone. Therefore, seconds elapse since the epoch is not variable depending on your geographical location. However, same cannot be said of struct_time. Object representation of Python Time may or may not take your time zone into account. There are two ways to convert float representing seconds to struct_time: UTC Local Time to convert Python Time float to UTC - base struct_time, Python Time module provides a function called gmtime. You use this call to discover your systems epoch. Now, you have a better foundation for understanding what is actually happening here. Gmtime converts the number of elapsed seconds since epoch to struct_time in UTC. In this case, youve passed 0 as number of seconds, meaning youre trying to find the epoch, itself, in UTC. As you saw before, struct_time cannot represent fractional seconds, so gmtime ignores fractional seconds in argument: notice that even though the number of seconds you passed was very close to 2,. 99 fractional seconds were simply ignore, as shown by tm_sec = 1. Secs parameter for gmtime is optional, meaning you can call gmtime with no arguments. Doing so will provide current Time in UTC: interestingly, there is no inverse for this function within Time. Instead, you have to look in the Python calendar module for the function name timegm:. Timegm takes tuple and returns corresponding number of seconds since epoch. Working with UTC is valuable in programming because of its standard. You do have to worry about DST, time zone, or locale information. That say, there are plenty of cases when you want to use Local Time. Next, youll see how to convert from seconds to Local Time so that you can do just that.


Starting Your PyCon Countdown #

Now you have enough information to start working on the countdown clock for next year's PyCon US! Pycon US 2021 will start on May 12 2021 in Pittsburgh, PA. With the 2020 event having been cancel, many Pythonistas are extra excited about next year's gathering. This is a great way to keep track of how long youll need to wait and boost your datetime skills at the same time! To get start, create a file called pyconcd. Py and add this code: in this code, you import datetime from datetime and define a constant, PYCON_DATE, that stores the date of the next PyCon US. You dont expect the date of PyCon to change, so you name variable in all caps to indicate that its constant. Next, you compute the difference between datetime. Now, which is current time, and PYCON_DATE. Taking the difference between two datetime instances returns datetime. Timedelta instance. Timedelta instances represent change in time between two datetime instances. Delta in name is a reference to the Greek letter delta, which is used in science and engineering to mean change. Youll learn more later about how to use timedelta for more general arithmetic operations. Finally, print output, as of April 9 2020 at little before 9: 30 PM is: only 397 days until PyCon US 2021! This output is a little clunky, so later on youll see how you can improve formatting. If you run this script on different day, youll get different output. If you run script after May 12 2021 at 8: 00 AM, youll get a negative amount of time remaining!


Understanding Time Zones #

One reason that dateutil is so useful is that it includes an interface to IANA Time zone database. This takes the hassle of assigning time zones to your datetime instances. Try out this example to see how to set datetime instance to have your local time zone: in this example, you import TZ from dateutil and datetime from datetime. You then create a datetime instance set to the current time now. You also pass tz keyword to. Now and set tz equal to tz. Tzlocal. In dateutil, tz. Tzlocal returns concrete instance of datetime. Tzinfo. This means that it can represent all necessary time zone offset and Daylight saving Time information that datetime needs. You also print the name of the time zone using. Tzname, which prints Eastern Standard Time. This is output for Windows, but on macOS or Linux, your output might read EST if youre in the US Eastern Time zone during winter. You can also create time zones that are not the same as time zone reported by your computer. To do this, youll use tz. Gettz and pass the official IANA name for the time zone youre interested in. Here is an example of how to use TZ. Gettz: In this example, you use TZ. Gettz to retrieve time zone information for London, United Kingdom and store it in London_tz. You then retrieve the current time, setting the time zone to London_tz. On Windows, this gives tzinfo attribute value tzfile. On macOS or Linux, tzinfo attribute will look something like tzfile, but it might be slightly different depending on where the dateutil pulls time zone data from. You also use tzname to print the name of the time zone, which is now GMT, meaning Greenwich Mean Time. This output is the same on Windows, Macos, and Linux. In the earlier section, you learn what you shouldnt use. You to create a datetime instance at current UTC. Now you know how to use dateutil. Tz to supply Time zone to datetime instance. Here is an example modified from recommendation in the Python documentation: in this code, you use TZ. Utc to set a time zone of datetime. Now to UTC Time zone. This method is recommended over using UTCNOW because utcnow returns naive datetime instance, whereas the method demonstrated here returns aware datetime instance. Next, youll take a small detour to learn about naive vs aware datetime instances. If you already know all about this, then you can skip ahead to improve your PyCon countdown with time zone information.


Using the Python datetime Module #

Minimum value of year is 1. This is what MINYEAR returns. 1 Both MAXYEAR and MINYEAR are of type integer. Bonus - type is of type type. < Class type > Other than these constants, Datetime has these Datetime class types: class Datetime. Date Python Date is an idealized naive date considering the current Gregorian calendar. Attributes: year, month, and day. Class Datetime. Time Python time is an idealized time, independent of any particular day. Here, we assume that each day is made of exactly 24 * 60 * 60 seconds. Attributes: hour, minute, second, microsecond, and tzinfo. Class Datetime. Datetime When you combine date and time, you get Datetime. False Attributes: year, month, day, hour, minute, second, microsecond, and tzinfo. Class Datetime. Timedelta timedelta is duration expressing difference between two Date, time, or Datetime instances to microsecond resolution. Class Datetime. Tzinfo tzinfo is abstract base class we use for time zone information objects. Date and time classes use it to provide customizable notions of time adjustment for example, to account for time zone and / or DST. Class Datetime. Timezone timezone implements tzinfo abstract base class as fixed offset from UTC. Such objects are immutable. Also, objects of type Date are naive, but those of types time or Datetime may be aware or naive. Next in the Python Datetime Module Tutorial is Date Objects

Aware and Naive Objects A

By default, all datetime objects are naive. To make them timezone - aware, you must attach tzinfo object, which provides UTC offset and timezone abbreviation as function of date and time. For time zones that are fixed offset from UTC, in Python 3. 2 +, datetime module provides timezone class, concrete implementation of tzinfo, which takes timedelta and name parameter: for Python versions before 3. 2, it is necessary to use a third party library, such as dateutil. Dateutil provides an equivalent class, tzoffset, which takes arguments from dateutil. Tz. Tzoffset, where offset is specified in seconds: for zones with daylight savings time, Python standard libraries do not provide standard class, so it is necessary to use a third party library. Pytz and dateutil are popular libraries providing time zone classes. In addition to static time zones, dateutil provides time zone classes that use daylight savings time. You can use Tz. Gettz method to get time zone object, which can then be passed directly to the datetime constructor: CAUTION: As of version 2. 53, dateutil does not handle ambiguous datetimes correctly, and will always default to a later date. There is no way to construct object with dateutil timezone representing, for example, 2015 - 11 - 01 1: 30 EDT - 4, since this is during daylight savings time transition. All edge cases are handled properly when using pytz, but pytz time zones should not be directly attached to time zones through constructor. Instead, pytz time zone should be attached using the time zone's localize method: be aware that if you perform datetime arithmetic on pytz - aware time zone, you must either perform calculations in UTC, or you must call normalize on result:

timedelta Objects A

Instance attributes (read-only):

AttributeValue
daysBetween -999999999 and 999999999 inclusive
secondsBetween 0 and 86399 inclusive
microsecondsBetween 0 and 999999 inclusive

Time values are represented with time class. Times have attributes For hour, minute, second, and microsecond. They can also include time zone information. Arguments to initialize time instance are optional, but default of 0 is unlikely to be what you want. Time, for instance, only holds values of time, and not date associated with time. Min and max class attributes reflect valid range of times in a single day. In fact, using floating point numbers for microsecond argument generates a TypeError. Calendar date values represent date class. Instances have attributes For year, month, and day. It is easy to create a date representing today's date using today's class method. There are also class methods for creating instances from integers or POSIX timestamp values. This example illustrates different value types used by fromordinal and fromtimestamp. As with time, range of date values support can be determined using min and max attributes. Another way to create a new date is use replace method of existing date. For example, you can change year, leaving day and month alone. Using replace is not the only way to calculate future / past dates. You can use datetime to perform basic arithmetic on date values via timedelta class. Subtracting dates produce timedelta, and timedelta can be added or subtracted from date to produce another date. Internal values for timedelta are stored in days, seconds, and microseconds. Intermediate level values passed to constructor are converted into days, seconds, and microseconds.

Broadly speaking, dstrftime acts like Time moduleas Time. Strftimefmt, dtimetuple although not all objects support the timetuple method. Conversely, datetime. The Strptime class method creates a datetime object from strings representing date and time and corresponding format string. Datetime. Strptime is equivalent to datetime * Time. Strptime, except when format, includes sub - second components or timezone offset information, which are supported in datetime. Strptime but is discarded by Time. Strptime. For time objects, format codes for year,s month,ss and days should not be used as time objects have no such values. If they used anyway, 1900 is substitute for year, and 1 for month and day. For date objects, format codes for hours, minutes, seconds, and microseconds should not be used as date objects have no such values. If they are used anyway, 0 is a substitute for them. The full set of format codes support varies across platforms, because Python calls platform C libraryas strftime function, and platform variations are common. To see the full set of format codes supported on your platform, consult strftime documentation. For the same reason, handling of format strings containing Unicode code points that canat be represented in charset of current locale is also platform - dependent. On some platforms, such code points are preserve intact in output, while on others, strftime may raise UnicodeError or return empty string instead. The following is a list of all format codes that C Standards require, and these work on all platforms with Standard C implementation. Note that the 1999 version of C Standard added additional format codes. The exact range of years for which strftime work also varies across platforms. Regardless of platform, years before 1900 cannot be used Because format depends on current locale, care should be taken when making assumptions about output value. Field orderings will vary, and output may contain Unicode characters encoded using localeas default encoding. When used with the strptime method,% P directive only affects output hour field if the% I directive is used to parse hour.S Unlike the time module, datetime module does not support leap seconds.% F is an extension to the set of format characters in C Standard. When used with the strptime method,% F directive accepts from one to six digits and zero pads on right. New in version 2. 6 For naive object,% Z and% Z format codes are replaced by empty strings. For awareness object:% Z utcoffset is transformed into a 5 - character string of form + HHMM or - HHMM, where HH is a 2 - digit string giving the number of UTC offset hours, and MM is a 2 - digit string giving the number of UTC offset minutes. For example, if utcoffset returns timedelta,% Z is replaced with string - 0330.

Technical Detail A

One of the ways you can manage the concept of Python Time in your application is by using floating point numbers that represent the number of seconds that have passed since the beginning of erathat is, since certain starting point. Let's dive deeper into what that mean, why it is useful, and how you can use it to implement logic, based on Python Time, in your application. You learn in the previous section that you can manage Python Time with floating point number representing elapsed time since the beginning of the era. Fix point in time from which series of years is reckoned system of chronological notation computed from give date as basis important concept to grasp here is that, when dealing with Python Time, youre consider the period of time identified by starting point. In computing, you call this starting point epoch. The Epoch, then, is the starting point against which you can measure the passage of time. For example, if you define the epoch to be midnight on January 1 1970 UTCthe, epoch as defined on Windows and most UNIX systemsthen you can represent midnight on January 2 1970 UTC as 86400 seconds since epoch. This is because there are 60 seconds per minute, 60 minutes per hour, and 24 hours per day. January 2 1970 UTC is only one day after the epoch, so you can apply basic math to arrive at that result: it is also important to note that you can still represent time before the epoch. Number of seconds would just be negative. For example, you would represent midnight on December 31 1969 UTC as - 86400 seconds. While January 1 1970 UTC is a common epoch, it is not the only epoch used in computing. In fact, different operating systems, filesystems, and APIs sometimes use different epochs. As you saw before, UNIX systems define epoch as January 1 1970. Win32 API, on the other hand, defines the epoch as January 1 1601. Youll learn about gmtime and struct_time throughout the course of this article. For now, just know that you can use Time to discover epochs using this function. Now that you understand more about how to measure time in seconds using epoch, let's take a look at the Python Time module to see what functions it offers that help you do so. First, Time. Time returns the number of seconds that have passed since the epoch. The return value is floating point number to account for fractional seconds: number you get on your machine may be very different because the reference point considered to be epoch may be very different. Measuring time in seconds is useful for a number of reasons: you can use float to calculate the difference between two points in time. Float is easily serializable, meaning that it can be stored for data transfer and come out intact on other side.


Python Time as an Object #

In your application, you may need to work at local time rather than UTC. The Python Time module provides a function for getting local time from the number of seconds that elapse since an epoch is called localtime. Signature of localtime is similar to gmtime in that it takes optional secs argument, which it uses to build struct_time using your local time zone: notice that tm_isdst = 0. Since DST matters with local time, tm_isdst will change between 0 and 1 depending on whether or not DST is applicable for given time. Since tm_isdst = 0, DST is not applicable for March 1, 2019. In the United States in 2019, daylight savings time begins on March 10. So, to test if the DST flag will change correctly, you need to add 9 days worth of seconds to secs argument. To compute this, you take the number of seconds in day and multiply that by 9 days: now, youll see that struct_time shows the date March 10 2019 with tm_isdst = 1. Also, notice that tm_hour has also jumped ahead, to 8 instead of 7 in previous example, because of daylight savings time. Since Python 3. 3, struct_time has also included two attributes that are useful in determining the time zone of struct_time: tm_zone tm_gmtoff at first, these attributes were platform dependent, but they have been available on all platforms since Python 3. 6 here, you can see that localtime returns to struct_time with the time zone set to CST. As you saw before, you can also tell the time zone based on two pieces of information, UTC offset and DST: in this case, you can see that current_local is 21600 seconds behind GMT, which stands for Greenwich Mean Time. Gmt is time zone with no UTC offset: UTC00: 00. 21600 seconds divided by seconds per hour means that the current_local time is GMT - 06: 00. You can use GMT offset plus DST status to deduce that current_local is UTC - 06: 00 at Standard Time, which corresponds to Central Standard Time zone. Like gmtime, you can ignore the second argument when calling localtime, and it will return to current local time in struct_time: unlike gmtime, inverse functions of localtime do exist in the Python Time module. Let's take a look at how that work.
