> from django.utils import timezone > aware = timezone. You can’t always subtract one year directly from a given date: Their values should be in UTC (or both!).įinally, our calendar system contains interesting edge cases.

To transmitĭatetimes safely, their representation should include the UTC offset, or If your application connects to other systems – for instance, if it queriesĪ web service – make sure datetimes are properly specified. Shoot yourself in the foot by carelessly turning naive datetimes into aware You’re better protected from DST-related bugs, but you can still Or datetime arithmetic is a candidate for subtle bugs that will bite youįor these reasons, time zone support is enabled by default in new projects,Īnd you should keep it unless you have a very good reason not to. On the other hand, bugs caused by the lack of time zone support are much

You’ll quickly learn how to avoid invalid You’re using naive datetimes where Django expects aware datetimes. When you enable time zone support, you’ll encounter some errors because This shields you from subtle and unreproducible bugs around When time zone support is enabled, Django uses a more accurate model

This can be done incrementally.ĭ defines some handy helpers for compatibilityįinally, in order to help you locate code that needs upgrading, Django raisesĪ warning when you attempt to save a naive datetime to the database: So the second step is to refactor your code wherever you instantiate datetime

With a naive datetime that you’ve created in your code. Since Django now gives you aware datetimes, you’ll getĮxceptions wherever you compare a datetime that comes from a model or a form To run into a few problems because it’s impossible to compare a naive datetime

However, these conversions may fail around DST transitions, which means youĪren’t getting the full benefits of time zone support yet. Objects in your code, Django makes them aware when necessary. At this point, things should mostly work. The first step is to add USE_TZ = True to your settingsįile. To enable it, set USE_TZ = True in your settings file. Time zone support is disabled by default. Solution to this problem is to use UTC in the code and use local time only when Or under bill your customers by one hour, twice a year, every year. This probably doesn’t matter for your blog, but it’s a problem if you over bill You’re likely to encounter errors twice a year, when the transitions happen. Many countries have a system of DST, where clocks are movedįorward in spring and backward in autumn. Practice to store data in UTC in your database. This is handy if your users live in more than one time zone and you want toĭisplay datetime information according to each user’s wall clock.Įven if your website is available in only one time zone, it’s still good Translates them to the end user’s time zone in templates and forms. UTC in the database, uses time-zone-aware datetime objects internally, and Once you have a datetime object, you can use the strftime() method to format the date and time values as strings, and the astimezone() method to convert the datetime object to a different timezone.When support for time zones is enabled, Django stores datetime information in The dateutil module provides additional tools for working with dates and times, such as the ability to parse date and time strings and convert between timezones. The time module provides functions for working with time values, such as the gmtime() and localtime() functions, which return a time structure representing the current date and time in the UTC and local timezones, respectively. You can also use the datetime() constructor to create a datetime object for a specific date and time. You can use the datetime.now() function to get the current date and time in the local timezone, or the datetime.utcnow() function to get the current date and time in the UTC timezone. In summary, the datetime module is a convenient and powerful tool for working with dates, times, and timestamps in Python. I hope these examples have helped you understand how to get the current date and time in Python, and how to convert between timezones.
