Follow your parish

These are the general fasting rules of the Orthodox Church, computed for both calendars. Local custom, age, health, pregnancy and your priest’s guidance come first — when in doubt, ask your priest.

Old and New Calendar

New Calendar (Revised Julian) churches — most Greek, Antiochian, OCA, Romanian and Bulgarian parishes — keep fixed feasts on the civil date. Old Calendar (Julian) churches — Russian, Serbian, Georgian and others — keep them 13 days later on the civil calendar. Pascha and the feasts that depend on it fall on the same day for both.
