A second view suggests that December 25 became the date of Jesus’ birth by a priori reasoning that identified the spring equinox as the date of the creation of the world and the fourth day of creation, when the light was created, as the day of Jesus’ conception (i.e., March 25). December 25, nine months later, then became the date of Jesus’ birth. For a long time the celebration of Jesus’ birth was observed in conjunction with his baptism, celebrated January 6. Christmas began to be widely celebrated with a specific liturgy in the 9th century but did not attain the liturgical importance of either Good Friday or Easter, the other two major Christian holidays. Roman Catholic churches celebrate the first Christmas mass at midnight, and Protestant churches have increasingly held Christmas candlelight services late on the evening of December 24.
