When is Presentation of the Lord (Candlemas)?

22And when the days of her purification according to the law of Moses were accomplished, they brought him to Jerusalem, to present him to the Lord; 23(As it is written in the law of the Lord, Every male that openeth the womb shall be called holy to the Lord;) 24And to offer a sacrifice according to that which is said in the law of the Lord, A pair of turtledoves, or two young pigeons. 25And, behold, there was a man in Jerusalem, whose name was Simeon; and the same man was just and devout, waiting for the consolation of Israel: and the Holy Ghost was upon him. 26And it was revealed unto him by the Holy Ghost, that he should not see death, before he had seen the Lord’s Christ. 27And he came by the Spirit into the temple: and when the parents brought in the child Jesus, to do for him after the custom of the law, 28Then took he him up in his arms, and blessed God, and said, 29Lord, now lettest thou thy servant depart in peace, according to thy word: 30For mine eyes have seen thy salvation, 31Which thou hast prepared before the face of all people; 32A light to lighten the Gentiles, and the glory of thy people Israel. 33And Joseph and his mother marvelled at those things which were spoken of him.
