Why is Christmas on December 25?

Have you ever wondered why Christmas is on December 25th? Okay, admit it! You have wondered. Raymond de Souza writes this about it:

For much of history, it was thought that Christmas was set on Dec. 25 to displace a pagan festival in honour of Mithras. More recent scholarship reveals it was the opposite. It was March 25 that was set as the great day of God's initiative, and thus for what is known as the Annunciation — the visit of Archangel Gabriel to Mary in Nazareth and the virginal conception of Jesus. Christmas was then set nine months later.
