[SOLVED] In python, how do I create a timezone aware datetime from a date and time?

In python, how do I create a timezone aware datetime from a date and time?

In Python, let's say I have a date of 25 December 2016. How can I create a timezone-aware datetime of noon on that date?

Bonus points if it's compatible with Django's timezone handling.

Solution

The trick is to first combine the naive time and the date into a naive datetime. This naive datetime can then be converted to an aware datetime.

The conversion can be done using the third party package pytz (using, in this case, the 'Europe/London' timezone):

import datetime
import pytz

naive_time = datetime.time(0, 30)
date = datetime.date(2016, 12, 25)
naive_datetime = datetime.datetime.combine(date, naive_time)

timezone = pytz.timezone('Europe/London')
aware_datetime = timezone.localize(naive_datetime)

If you're doing it in Django, and want to use the current timezone (as configured in Django), you can replace the final two lines with a call to make_aware:

from django.utils import timezone

aware_datetime = timezone.make_aware(naive_datetime)
