Many religions involve following a religious or liturgical calendar. It might not even be a liturgical calendar but a cultural one associated with a religion. Is there a calendar that you follow in your religion? If so, do you keep up with it every day of your life, or do you only keep up with significant dates on that calendar?
Example calendars are the Vikrami Calendar, the Tamil Calendar, the Nanakshahi Calendar, the Hebrew/Jewish Calendar, the Revised Julian Calendar, the Islamic Calendar, and the Zoroastrian Calendar. Polytheistic reconstructionists/revivalists might follow the Attic Calendar, the Macedonian Calendar, or the Kemetic/Egyptian/Sopdet Calendar, as examples.
