Your Own Python Calendar

The Python calendar module defines the Calendar class. This is used for various date calculations as well as TextCalendar and HTMLCalendar classes with their local subclasses, used for rendering pre-formatted output.

Import the module:

import calendar

Print the current month:

import calendar
year = 2016
month = 1
cal = calendar.month(year, month)
print(cal)

The output will look like this:

           January 2016
      Mo Tu We Th Fr Sa Su
                   1  2  3
       4  5  6  7  8  9 10
      11 12 13 14 15 16 17
      18 19 20 21 22 23 24
      25 26 27 28 29 30 31

Set the first day of the week as Sunday:

calendar.setfirstweekday(calendar.SUNDAY)

To print a whole year’s calendar:

print(calendar.calendar(2016))

Output not shown since it is too large.

This module provides other useful methods for working with dates, times and calendars such as calendar.isleap (checks if a year is a leap year).
