<p><strong>Source code:</strong> <a class="extlink-source reference external" href="https://github.com/python/cpython/tree/3.13/Lib/calendar.py">Lib/calendar.py</a></p>
<hr class="docutils" />
<p>This module allows you to output calendars like the Unix <strong class="program">cal</strong> program,
and provides additional useful functions related to the calendar. By default,
these calendars have Monday as the first day of the week, and Sunday as the last
(the European convention). Use <a class="reference internal" href="#calendar.setfirstweekday" title="calendar.setfirstweekday"><code class="xref py py-func docutils literal notranslate"><span class="pre">setfirstweekday()</span></code></a> to set the first day of
the week to Sunday (6) or to any other weekday. Parameters that specify dates
are given as integers. For related
functionality, see also the <a class="reference internal" href="datetime.html#module-datetime" title="datetime: Basic date and time types."><code class="xref py py-mod docutils literal notranslate"><span class="pre">datetime</span></code></a> and <a class="reference internal" href="time.html#module-time" title="time: Time access and conversions."><code class="xref py py-mod docutils literal notranslate"><span class="pre">time</span></code></a> modules.</p>
<p>The functions and classes defined in this module
use an idealized calendar, the current Gregorian calendar extended indefinitely
in both directions. This matches the definition of the “proleptic Gregorian”
calendar in Dershowitz and Reingolds book “Calendrical Calculations”, where
its the base calendar for all computations. Zero and negative years are
interpreted as prescribed by the ISO 8601 standard. Year 0 is 1 BC, year -1 is
2 BC, and so on.</p>
