 In the Catholic tradition it begins with a three-day "rogation" to ask for God's mercy, and the feast itself includes a procession of torches and banners symbolising Christ's journey to the Mount of Olives and entry into Heaven, the extinguishing of the Paschal candle, and an all-night vigil; white is the liturgical colour.The Eastern Orthodox tradition has a slightly different calendar up to a month later than in the Western tradition.The feast was retained at the Protestant Reformation.
