Python - Run Job every first Monday of month

Question

Background: I need to run automatic tasks every first and third monday of the month for a server. This should be realised via python not crontab.

I found the python module "schedule" but its documentation is not detailed. https://pypi.org/project/schedule/

https://schedule.readthedocs.io/en/stable/

Does anybody know how to do this?

import schedule

def TestFunction():
    pass

schedule.every(1).monday.do(TestFunction)
schedule.every(3).monday.do(TestFunction)
schedule.run_pending()

Will this be executed on the first monday of the year, month or every monday?

Answer 1

Here's a possible solution:

import datetime

def something():
    day_of_month = datetime.now().day
    if (day_of_month > 7 and day_of_month < 15) or day_of_month > 21:
        return # not first / third monday of month
    # your code

schedule.every().monday.do(something())

The scheduler will run every monday, but we return if this is not the first / third monday of the month.
