<p style="color: grey"> Python recipe 576518 by <a href="/recipes/users/4167352/">Martin Diers</a> (<a href="/recipes/tags/calendar/">calendar</a>, <a href="/recipes/tags/church/">church</a>). </p> <p>When initialized with a <code>year</code>, returns a class with a number of date attributes corresponding to common feasts of the western liturgical calendar. Number of Sundays after Epiphany and Trinity / Pentecost are also calculated, and stored in attributes. If the optional parameter <code>v2</code> is set to True, the calendar will return a post-Vatican II calendar which changes the date of Transfiguration Sunday, and the number of Sundays after Epiphany. In either case, the pre-Lent Sundays and Sundays after Pentecost will be set.</p> <p><strong>Note:</strong> The <code>year</code> parameter is the year of the First Sunday in Advent - the beginning of the church year, and the resulting calendar thus ends in the following year.</p>
