Note: The Byzantine liturgical year starts on September 1 and ends on August 31. The movable feasts are determined by the date of Pascha (the feast of the Resurrection). There are two systems currently in use to calculate Pascha - Gregorian (Western) and Julian (Eastern). Roman Catholics, most Byzantine Catholics in America and some Orthodox (notably those in Finland) follow the Gregorian date. Some Byzantines in America and most Byzantines and Orthodox in Canada and elsewhere follow the Julian date. In the year AD 2023 the Gregorian date is April 9 and the Julian date is April 16.
