Some people place Jesus's birth in April
but that would be too close to Easter, when Jesus died and rose from the dead. So they had to find another season to place Christmas in. Seems like December was a better choice, near Haunaka and other celebrations from other religions. Of course it looks like some things were borrowed from other religions as well. Trees, Mistletoe, Gifts, Elves, Santa's magic to name a few. Problem is that these things make people forget about Jesus. Ask a child about Christmas and they will respond Satna Claus instead of Jesus most of the time. Why? Because it isn't Jesus giving them gifts, it is Santa Claus. To them Jesus is that baby born in the Manger placed under the tree. The one that the Wise Men or Three Kings gave gifts to.
