Python DateTime weekday() Method with Example

In this article, we will discuss the weekday() function in the DateTime module. weekday() function is used to get the week number based on given DateTime. It will return the number in the range of 0-6

Representation	Meaning
0	Monday
1	Tuesday
2	Wednesday
3	Thursday
4	Friday
5	Saturday
6	Sunday

It will take input as DateTime in the format of “(YYYY, MM, DD, HH, MM, SS)”, where,

• YYYY stands for year
• MM stands for Month
• DD stands for Date
• HH stands for Hour
• MM stands for minute
• SS stands for second

We first need to import the DateTime module and create a DateTime, now using weekday() function we will get the weekday for a particular DateTime.

Syntax:

datetime(YYYY,MM,DD, HH,MM,SS).weekday()

we can also extract date from DateTime by using the following syntax:

Syntax:

datetime(YYYY,MM,DD, HH,MM,SS).date()

Example: Python program to create DateTime and display DateTime and date

Python3

# importing datetime class
from datetime import datetime

# create datetime
x = datetime(2021, 8, 8, 12, 5, 6)

# display
print("Datetime is :", x)


# get the date
print("Date is :", x.date())

Output:

Datetime is : 2021-08-08 12:05:06

Date is : 2021-08-08

Example: Python program to get the weekdays for the given datetime(s)

Python3

# importing datetime class
from datetime import datetime

# create datetime
x = datetime(2021, 8, 8, 12, 5, 6)

# display
print("Datetime is :", x)


# get the weekday
print("weekday is :", x.weekday())


# create datetime
x = datetime(2021, 9, 10, 12, 5, 6)

# display
print("Datetime is :", x)


# get the weekday
print("weekday is :", x.weekday())

# create datetime
x = datetime(2020, 1, 8, 12, 5, 6)

# display
print("Datetime is :", x)


# get the weekday
print("weekday is :", x.weekday())

Output:

Datetime is : 2021-08-08 12:05:06

weekday is : 6

Datetime is : 2021-09-10 12:05:06

weekday is : 4

Datetime is : 2020-01-08 12:05:06

weekday is : 2

Example 3: Python program to get the name of weekday

Python3

# create a list of weekdays
from datetime import datetime

days = ["Monday", "Tuesday", "Wednesday",
        "Thursday", "Friday", "Saturday", "Sunday"]

# importing datetime class

# create datetime
x = datetime(2021, 8, 8, 12, 5, 6)

# display
print("Datetime is :", x)


# get the weekday name using index
print("weekday is :", days[x.weekday()])


# create datetime
x = datetime(2021, 9, 10, 12, 5, 6)

# display
print("Datetime is :", x)


# get the weekday name  using index
print("weekday is :", days[x.weekday()])

# create datetime using index
x = datetime(2020, 1, 8, 12, 5, 6)

# display
print("Datetime is :", x)


# get the weekday name using index
print("weekday is :", days[x.weekday()])

Output:

Datetime is : 2021-08-08 12:05:06

weekday is : Sunday

Datetime is : 2021-09-10 12:05:06

weekday is : Friday

Datetime is : 2020-01-08 12:05:06

weekday is : Wednesday
