The Bible does not tell us when Jesus was born. However, it does give us a sound reason to conclude that his birth did not take place in December. Specifically, it was written in the Bible that when Jesus was born that there were "shepherds in the fields tending their flocks on the night" (Luke 2:8-12). Take note that the shepherds were actually living out of doors, not just strolling outside during the day. They had their flocks in the fields at night. Does that description of outdoor living fit the chilly and rainy weather conditions of Bethlehem in December? No, it does not.
