Christmas happens one time a year. Its happens every year on December 25. Christmas was started when Jesus Christ, the son of God was born in Bethlehem. The day before Christmas day is called Christmas Eve.
What most people do on Christmas is they all go over to one of their families houses. When they go to their families houses they bring over their presents for each other. Each family does Christmas different. Some families open their presents on Christmas Eve or Christmas morning. Christmas is also one of the days that you get really stuffed with food. You do because most families have a really big breakfast and a really big dinner.
A lot of people think Christmas is only meant for spending time with your families. Christmas is meant for that, but it is also meant for celebrating Jesus's birthday, Gods gift to us.
