The calendar Module

The calendar module is a Python reimplementation of the Unix cal command. It simply prints the calendar for any given month or year to standard output.

In Example 14-12, prmonth(year, month) prints the calendar for a given month.

Example 14-12. Using the calendar Module

File: calendar-example-1.py

import calendar
calendar.prmonth(1999, 12)

Note that the calendars are printed using European conventions; in other words, Monday is the first day of the week.

This module contains a number of support functions that can be useful if you want to output calendars in other formats. Its probably easiest to copy the entire file, and tweak it to suit your needs.
