The Maronite Church observes a liturgical year organized around a unique system of liturgical seasons (Shhitun), beginning with the season of the Announcement (Advent/Sawmo d-Sohoro) and proceeding through the Nativity, Epiphany, Great Lent, Holy Week, Pentecost, and the long 'Season of the Apostles.' This calendar preserves ancient Antiochene structures while incorporating Roman feast dates following Latinization.

Marian feasts hold a preeminent place in the Maronite calendar, including the feast of Our Lady of Lebanon (first Sunday of May), the Annunciation, the Dormition/Assumption, the Nativity of the Theotokos, and the Immaculate Conception. The feast of St. Maron (February 9) is the principal patronal celebration. The feasts of St. Sharbel Makhluf (July 24) and Blessed Rafqa (March 23) are also widely celebrated. The Maronite calendar follows the Gregorian system, so major feasts align with the Western Christian calendar.
