An All-Night Vigil (Greek: Agrypnia, "without sleeping"; Slavonic: Vsenoshnoe Bdenie) is a combination of multiple services whose makeup varies significantly according to regional and local tradition. In the Byzantine tradition, the service lasts through the night, consisting of the entire liturgical cycle, culminating in the Divine Liturgy. In Slavic tradition, it does not last all night but normally includes Vespers (or Great Compline), Orthros and the First Hour, and it is the standard Saturday evening service. When the Vigil is celebrated, the particular rubrics for its constituent services are altered.
