If you still worship Saturn then I hope you have a happy winter solstice. There are many people complaining that Christmas hijacked Saturnalia. Well, they are partially right. Christmas used to be celebrated in the springtime but many were feeling left out by not participating in the drunken debauchery fest known as Saturnalia.
The church decided to move Christmas to December as a rival celebration. This would give Christians something else to do rather than eating and drinking until they vomited and other such merrymaking. Just to be clear, Christmas is not pagan in origin but some winter celebrations are full-blown pagan. If anything paganism has crept back into Christmas.
