Convert datetime to Different Time Zone in Python (3 Examples)


This tutorial demonstrates how to convert the time zone of a datetime object to another time zone such as CET,CST,EAT, EST, and UTC in the Python programming language.

This article contains the sections below:

Let’s dive into the Python code!


Import datetime Module & Create Example Data

As a first step, we have to import the datetime module to Python:

from datetime import datetime

To specify the different time zones in Python, we also have to load the pytz module:

import pytz

Now, we can create a datetime object with the time zone UTC by applying the Python code below:

my_datetime = datetime(2023, 2, 13, 17, 10, 27, tzinfo = pytz.utc)
# 2023-02-13 17:10:27+00:00

We can also format our datetime object to show the time zone using the strftime function:

my_datetime_utc = my_datetime.strftime('%Y-%m-%d %H:%M:%S %Z%z')
# 2023-02-13 17:10:27 UTC+0000

As you can see, our example date and time are the 13th of February 2023 at 05:10:27pm.

Let’s convert this date and time to different time zones.


Example 1: Convert datetime to CET Time Zone

If we want to convert a datetime object to the CET time zone, we can use the astimezone function and the time zone ‘Europe/Berlin’ as shown below:

my_datetime_cet = my_datetime.astimezone(pytz.timezone('Europe/Berlin')).strftime('%Y-%m-%d %H:%M:%S %Z%z')
# 2023-02-13 18:10:27 CET+0100


Example 2: Convert datetime to CST Time Zone

Similar to the Python code of Example 1, we can convert our example datetime object to CST by specifying ‘US/Central’ within the timezone function:

my_datetime_cst = my_datetime.astimezone(pytz.timezone('US/Central')).strftime('%Y-%m-%d %H:%M:%S %Z%z')
# 2023-02-13 11:10:27 CST-0600


Example 3: Convert datetime to EST Time Zone

In case we want to convert our time zone to EST, we have to specify ‘US/Eastern’:

my_datetime_est = my_datetime.astimezone(pytz.timezone('US/Eastern')).strftime('%Y-%m-%d %H:%M:%S %Z%z')
# 2023-02-13 12:10:27 EST-0500

Not enough? You could have a look at some other tutorials here on Statistics Globe:

This post has shown how to transform datetime objects to other time zones in the Python programming language.

Note that we could use the code of this tutorial to convert datetime objects to many other time zones such as AEST, ACST, AFT, AKST, AST, CAT, EET, MSK, MST, PST, WAT, and WET as well. We simply would have to specify the corresponding region within the timezone function.

  • Hi, awesome tutorial!

    How can I use this on a list?
    I have a json file with startTime and endTime that I’d like to convert by one hour off (From Norway time to Sweden time)
    I have imported the json file and managed to set up the pytz, but I dont know how to use thr for loop for a timevalue?

    • Hello Mathias,

      You can use the following code segment:

      sweden_date_list = []
      for datetime in norway_date_list:

      This will yield a new list with the Sweden timezones in the order the dates were in the Norway timezone list.

      Please let us know if you have any further questions.
