How can I get the start and end dates for each week?

week =,4,10).isocalendar()[1]

After finding the week, how can I get the start and end date of the week?


  • Python 3.6 version of rshepp's answer:

    from datetime import datetime, date
    year, week, day = date(2022, 4, 10).isocalendar()
    date_first = datetime.strptime(f'{year}{week}0', '%Y%U%w')
    date_last = datetime.strptime(f'{year}{week}6', '%Y%U%w')
    print(date_first, date_last, sep='\n')

    Output, Sunday-Saturday

    2022-04-03 00:00:00
    2022-04-09 00:00:00

    date_first = datetime.strptime(f'{year}{week}1', '%Y%U%w')
    date_last = datetime.strptime(f'{year}{week+1}0', '%Y%U%w')
    print(date_first, date_last, sep='\n')

    Output, Monday-Sunday

    2022-04-04 00:00:00
