Saint Sylvester's Day
December 31, Sunday
Saint Sylvester's Day, also known as Silvester or the Feast of Saint Sylvester, is the day of the feast of Pope Sylvester I, a saint who served as pope (bishop of Rome) from 314 to 335. Medieval legend made him responsible for the conversion of emperor Constantine. Among the Western churches, the feast day is held on the anniversary of Saint Sylvester's death, 31 December, a date that, since the adoption of the Gregorian calendar, has coincided with New Year's Eve.
