Today the Church celebrates the feast of the Presentation of the Lord which occurs forty days after the birth of Jesus and is also known as Candlemas day, since the blessing and procession of candles is included in today's liturgy.
According to the 1962 Missal of Bl. John XXIII the Extraordinary Form of the Roman Rite, today is the end of the Christmas season. The reformed calendar has designated that the Sunday after Epiphany, the Feast of the Baptism of Our Lord, is the end. This feast in the Ordinary Form is no longer referred to as the "Purification of Mary" but the "Presentation of the Lord".
