utils.timezone.make_aware()

make_aware(value, timezone=None, is_dst=None) [source]

Returns an aware datetime that represents the same point in time as value in timezone, value being a naive datetime. If timezone is set to None, it defaults to the current time zone.

When pytz is installed, the exception pytz.AmbiguousTimeError will be raised if you try to make value aware during a DST transition where the same time occurs twice (when reverting from DST). Setting is_dst to True or False will avoid the exception by choosing if the time is pre-transition or post-transition respectively.

When pytz is installed, the exception pytz.NonExistentTimeError will be raised if you try to make value aware during a DST transition such that the time never occurred (when entering into DST). Setting is_dst to True or False will avoid the exception by moving the hour backwards or forwards by 1 respectively. For example, is_dst=True would change a non-existent time of 2:30 to 1:30 and is_dst=False would change the time to 3:30.

is_dst has no effect when pytz is not installed.
