THE ORTHODOX CHURCH CALENDAR
All that exists is created by God, even time and space itself. In offering everything we have back to God, we offer Him one of the most precious things we have: our time. By having a Church Calendar, we observe a rhythm of feasts and fasts, daily and weekly observances, all centered on Christ's Life, Death, & Resurrection. It is in this sanctification of time that even time itself brings us closer to God, shaping and restoring us to His Likeness.
The Church Calendar is made of two parts: immoveable and moveable. Feasts such as the Nativity of our Lord, Theophany, Feasts of the Mother of God and most saints are immovable, always taking place on a fixed date. Other Feasts, such as Pascha (The Feast of Feasts!) and Pentecost are moveable feasts that are calculated year after year on a new date. By observing time and worship in this way, our worship has both a temporal and everlasting character, like Christ, subject to time but not confined by it.
Please note that St. Nicholas Church follows the "Old Calendar", the Julian Calendar. On the common calendar, certain feasts such as the Nativity of our Lord/Christmas (Dec. 25/Jan. 7) and Theophany (Jan. 6/Jan. 19) will take place 13 days later than those on a revised or newer calendar.
