why christmas is on 25th december

The reason we celebrate Christmas on the 25th of December is because it marks the date of Jesus Christ's birth. The date was first established by Pope Julius I in 350 A.D., and the holiday has been celebrated on this day ever since. It is believed that Jesus was born on this day because the Bible tells us that shepherds were out in the fields at night and that the Wise Men followed a star to Bethlehem. This suggests that Jesus was born during the winter months, when the nights were long and the skies were clear.
