The Byzantine Rite has three basic types of vespers: great, daily, and small. Great vespers is used on Sundays and major feast days (those when the Polyeleos is prescribed at matins) when it may be celebrated alone or as part of an All-Night Vigil, as well as on a handful of special days "e.g.", Good Friday and Pascha afternoon; on certain days of strict fasting it also commences the divine liturgy. Daily vespers is otherwise used. Small vespers is a very abbreviated form used only on the afternoon before a vigil and is redundant to the subsequent great vespers, being a placeholder between the ninth hour and compline and is seldom used except in monasteries, where the vigil can last all night.
