Oh you poor poor person.
The exact date of Jesus’ birth as s not recorded. So, ultimately, it is not important. But does not knowing the exact date or day render celebration of that day impossible?
I would opine that it does not. We have that day/date to celebrate an event, the birth of the Savior of the world.
Good luck shopping at Wal-Mart for all your winter solstice gifts.
Enjoy your celebration, but please don’t imagine that the world revolves around your celebration.
Merry Christmas!
