when did the celebration of christmas start

The celebration of Christmas dates back to the early fourth century AD when Christianity was just beginning to spread throughout the world. In those days, Christians celebrated December 25th as the birthday of Jesus Christ, the savior of the world, and they marked this special occasion with a solemn ceremony to honor His birth. Over time, the ceremony evolved into what we know today as Christmas, a joyous occasion filled with celebration, gift-giving, and family gatherings.
