Nope, not really.
Very old records show that the belief was that Christ was incarnated in the spring, which could very well mean that his conception was at that time. March 25th (the feast of the Annunciation) was the best guess, given the ancient Jewish belief in the integral age of prophets and given that they thiought that He died on March 25th. IF Mary's pregnancy lasted exactly 9 months (the best guess, although by no means a certainty), that brings us to: December 25th!!
