Calendar Functions in Python - ( calendar(), month(), isleap()?)

We can perform the calendar operations using the calendar module in Python. Here, we are going to learn about the different methods of calendar class instance.

calendar.calendar(year)

The calendar class instance returns the calendar of the year. Let's see one example.

Example

 Live Demo

# importing the calendar module
import calendar
# initializing year
year = 2019
# printing the calendar
print(calendar.calendar(year))

Output

If you run the above code, you will get the following results.

calendar.firstweekday()

The method calendar.firstweekday() returns the first weekday in the week i.e.., MONDAY.

Example

 Live Demo

# importing the calendar
import calendar
# getting firstweekday of the year
print(calendar.firstweekday())

Output

If you run the above program, you will get the following results.

0

calendar.isleap(year)

The method calendar.isleap(year) returns whether the year is a leap or not. Let's take one example.

Example

# importing the calendar module
import calendar
# initializing years
year_one = 2019
year_two = 2020
# checking whether they are leap or not
print(f'{year_one} is leap year' if calendar.isleap(year_one) else f'{year_one} is
not a leap year')
print(f'{year_two} is leap year' if calendar.isleap(year_two) else f'{year_two} is
not a leap year')

Output

If you run the above code, you will get the following results.

2019 is not a leap year
2020 is leap year

calendar.WEEK_CONSTANT

There are WEEK_CONSTANTS in the calendar module to get the weekday number. Let's see examples.

Example

 Live Demo

# importing the calendar module
import calendar
# getting weekday numbers
print(f'Monday weekday: {calendar.MONDAY}')
print(f'Tuesday weekday: {calendar.TUESDAY}')
print(f'Wednesday weekday: {calendar.WEDNESDAY}')
print(f'Thursday weekday: {calendar.THURSDAY}')
print(f'Friday weekday: {calendar.FRIDAY}')
print(f'Saturday weekday: {calendar.SATURDAY}')
print(f'Sunday weekday: {calendar.SUNDAY}')

Output

If you run the above program, you will get the following results.

Monday weekday: 0
Tuesday weekday: 1
Wednesday weekday: 2
Thursday weekday: 3
Friday weekday: 4
Saturday weekday: 5
Sunday weekday: 6
