Often, you may want to modify existing datetime objects to represent a different date and time. This recipe includes code to demonstrate this.

How to do it…

Follow these steps to execute this recipe:

1. Import the necessary modules from the Python standard library:

>>> from datetime import datetime

2. Fetch the current timestamp. Assign it to dt1 and print it:

>>> dt1 = datetime.now()
>>> print(dt1)

We get the following output. Your output would differ:

2020-08-12 20:55:46.753899

3. Create a new datetime object by replacing the year, month, and day attributes of dt1. Assign it to dt2 and print it :

>>> dt2 = dt1.replace(year=2021, month=1, day=1)
>>> print(f'A timestamp from 1st January 2021: {dt2}')

We get the following output. Your output would differ:

A timestamp from 1st January 2021: 2021-01-01 20:55:46.753899
