How Can Python's `datetime` Module Help Determine a Date's Day of the Week?

How to Determine the Day of the Week for a Given Date

When working with dates, it often becomes necessary to determine the corresponding day of the week. Python's datetime module provides a convenient method to accomplish this task.

Getting the Day of the Week

To retrieve the day of the week from a datetime object, utilize the weekday() method. This method returns an integer representing the day of the week, with Monday being 0 and Sunday being 6.

>>> today = datetime.datetime(2017, 10, 20)
>>> today.weekday()
6

In this example, the output is 6, indicating that October 20, 2017, falls on a Friday.

Example: Retrieving the Day of the Week for Today

The datetime.datetime.today() method provides access to the current date and time. By combining this with weekday(), you can easily determine the day of the week for today:

>>> import datetime
>>> datetime.datetime.today()
datetime.datetime(2023, 3, 7, 15, 37, 51, 777063)
>>> datetime.datetime.today().weekday()
2

In this case, the output is 2, confirming that March 7, 2023, is a Tuesday.
