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>
