How to Quickly Find the First Day of a Month in Python

In some companies, they pay their employees on the first day of every month.

If you want to know what day of the week will that be, you can find that quickly in Python using the calendar module.

Let us assume that you want to check the first day of the next month:

 import calendar
 ​
 first_day, _ = calendar.monthrange(2022, 12)

Now we can simply check the day_name for that first_day value that we got from monthrange():

 import calendar
 ​
 # Get current month
 first_day, _ = calendar.monthrange(2023, 1)
 ​
 print(first_day)
 ​
 print(calendar.day_name[first_day])  # Thursday

That’s basically it.
