Python - Find all Sundays (or any other weekdays) between two dates

Here we will try to list out all the Sundays between any two dates.
This can be used to find any weekdays as well.

import datetime

startdate = datetime.datetime(2022, 1, 1)
enddate = datetime.datetime(2022, 1, 31)

dt = startdate
sundaylist = []
while dt < enddate:
    weekday = int(dt.strftime('%w'))
    if (weekday == 0): #Sunday
        sundaylist.append(dt)
    dt += datetime.timedelta(days=1)

#Result contains datetime objects. Convert to string, if needed.
stringdates = [ datetime.datetime.strftime(d, '%Y/%m/%d') for d in sundaylist]
print(stringdates)

Output: ['2022/01/02', '2022/01/09', '2022/01/16', '2022/01/23', '2022/01/30']

If dates are in string format, convert to the datetime object and apply the logic.

import datetime

sdt = '2022/2/1'
edt = '2022/2/28'

startdate = datetime.datetime.strptime(sdt, '%Y/%m/%d')
enddate = datetime.datetime.strptime(edt, '%Y/%m/%d')

dt = startdate
sundaylist = []
while dt < enddate:
    weekday = int(dt.strftime('%w'))
    if (weekday == 0): #Sunday
        sundaylist.append(dt)
    dt += datetime.timedelta(days=1)

stringdates = [ datetime.datetime.strftime(d, '%Y/%m/%d') for d in sundaylist]
print(stringdates)

Output: ['2022/02/06', '2022/02/13', '2022/02/20', '2022/02/27']
