The Feast of the Presentation of Our Lord, also known as Candlemas, dates back to at least the late 4th century. It was originally celebrated on February 15, 40 days after January 6. But, as December 25 became the standard date to celebrate Christ's birth, the date of the feast was moved back to February 2.
Under Mosaic Law, a woman was considered ritually unclean for 40 days after childbirth, after which, she was to offer a sacrifice for her purification. The feast, however, is more a celebration of the Christ's first appearance in the Temple than of Mary's purification.
Its alternate name of Candlemas dates from Pope Sergius in the early eighth century. He initiated a candlelight procession on this date. Later in the century, the blessing and distribution of candles was made on this date.
