The All-night vigil is a service of the Eastern Orthodox and Byzantine Catholic churches consisting of an aggregation of the canonical hours of Compline (in Greek usage only), Vespers (or, on a few occasions, Great Compline), Matins, and the First Hour. This service may be performed (commencing the evening before) on any Sunday or major feast,[1]
any feast for which a Litia is prescribed; these feasts are marked in the Typikon and in liturgical calendars by a Greek cross printed in red in a properly shaped semicircle [open at the top] (); this symbol is encoded in Unicode as U+1F541 (đ).
