Example 1: Use the datetime.weekday() Method in Python

from datetime import datetime

datetime_object = datetime.now()

print("Datetime is:", datetime_object)

dayNo = datetime_object.weekday()

print("Day of the week is:", dayNo)

This method comes in handy when we want to schedule our dates according to a particular day.

import datetime

weekDays = (
    "Monday",
    "Tuesday",
    "Wednesday",
    "Thursday",
    "Friday",
    "Saturday",
    "Sunday",
)

datetime_object = datetime.datetime(2022, 8, 22, 00, 00, 00)

dayNo = weekDays[datetime_object.weekday()]

print("{} is for {}".format(datetime_object, dayNo))

nextDay = datetime_object.replace(day=2)

dayNo = weekDays[nextDay.weekday()]

print("{} is for {}".format(nextDay, dayNo))

nextDay = datetime_object.replace(day=3)

dayNo = weekDays[nextDay.weekday()]

print("{} is for {}".format(nextDay, dayNo))

nextDay = datetime_object.replace(day=4)

dayNo = weekDays[nextDay.weekday()]

print("{} is for {}".format(nextDay, dayNo))

nextDay = datetime_object.replace(day=5)

dayNo = weekDays[nextDay.weekday()]

print("{} is for {}".format(nextDay, dayNo))

nextDay = datetime_object.replace(day=6)

dayNo = weekDays[nextDay.weekday()]

print("{} is for {}".format(nextDay, dayNo))

nextDay = datetime_object.replace(day=7)

dayNo = weekDays[nextDay.weekday()]

print("{} is for {}".format(nextDay, dayNo))

Output:

2022-08-22 00:00:00 is for Monday
2022-08-02 00:00:00 is for Tuesday
2022-08-03 00:00:00 is for Wednesday

2022-08-06 00:00:00 is for Saturday
2022-08-07 00:00:00 is for Sunday
