calendar Module

The calendar module provides functions for calendar-related operations and generating formatted calendars.

Basic Calendar Operations

Get calendar information for dates.

import calendar
from datetime import date

# Day of week for a specific date
d = date(2024, 12, 25)
day_name = calendar.day_name[d.weekday()]
print(f"2024-12-25 is a {day_name}")

# Check if leap year
print(f"2024 is leap year: {calendar.isleap(2024)}")
print(f"2025 is leap year: {calendar.isleap(2025)}")

# Days in month
days = calendar.monthrange(2024, 2)
print(f"Feb 2024 has {days[1]} days")

2024-12-25 is a Wednesday
2024 is leap year: True
2025 is leap year: False
Feb 2024 has 29 days
