Traditionally, Christ was believed to have been conceived and to have died on the same date, March 25. It is likely that the date of Christmas, therefore, is derived from the calculation of nine months after the feast of the Annunciation. That Christmas happened to become a rival to the pagan winter festival of Sol Invictus is a significant coincidence, but the two are not directly related, as is often asserted today.
