I love Christmas, the music, the food, the gifts and the stories as well as all the religious and spiritual traditions associated with the day. And, I'm all for holidays. The more the merrier. You can never have too many of them. And they never last long enough.
Federal holidays are relatively easy to declare.
All it takes is for the president and Congress to agree on a date and a reason. From what I've read on the subject, there are no set criteria. Establishing a federal holiday is not like nominating someone for sainthood. Still, Rick Ganulin has a point. Christmas is a Christian religious holiday and the United States government, by law, cannot endorse one faith over another.
