Question

How can I calculate the date of the next Friday?

Answer 1

import datetime 
def next_fri_13(start_date):
        next_friday = start_date + datetime.timedelta(((4 - today.weekday()) % 7))
        while True:
            if next_friday.day==13:
                thirteen_friday = next_friday
                break
            else:
                next_date = next_friday + datetime.timedelta(days=1)
                next_friday = next_date + datetime.timedelta(((4 -next_date.weekday())% 7))
        return thirteen_friday

    r = next_fri_13(datetime.date(2020, 2, 11)) print(r)
