St. Stephen's Day takes place on December 26, 2025. St. Stephen's Day, or the Feast of St. Stephen, is a Christian saint's day to commemorate Saint Stephen, celebrated on 26 December in the Western Church and 27 December in the Eastern Church. Many Eastern Orthodox churches adhere to the Julian calendar and mark St. Stephen's Day on 27 December according to that calendar, which places it on 9 January of the Gregorian calendar used in secular contexts. It commemorates St. Stephen, the first Christian martyr or protomartyr. (With material from: Wikipedia)
