Make Unaware datetime Time Zone Aware in Python (Example)


In this post, I’ll show how to make an unaware datetime time zone aware in the Python programming language.

This article contains the sections below:

Now, let’s get started!


Import Modules & Create Data

As a first step, we have to import two modules to Python: datetime and pytz.

import datetime
import pytz

Next, we have to create an exemplifying datetime object:

my_datetime_unaware = datetime.datetime(2021, 5, 25, 11, 12, 2, 0)
# 2021-05-25 11:12:02

As you can see, we have created a datetime object without an explicitly shown time zone.


Example : Display Time Using pytz.utc.localize()

This example illustrates how to properly display a time zone of a datetime object.

For this task, we can use the replace function and the tzinfo parameter as shown below:

my_datetime_aware = my_datetime_unaware.replace(tzinfo = pytz.UTC)
# 2021-05-25 11:12:02+00:00

As you can see, we have created a new data object containing the corresponding time zone.
