Actually ‘Christmas’ is a celebration of HIS conception... The shortest day of sun light on this earth God was with us on this earth. His birth was near the fall equinox. Christians either believe what HE said or else they do not. It is HIS conception that tells us that ‘life’ begins at conception...
It’s a Federal Holiday. I fail to see how, there is a violation of church and state or any other ridiculous claims when this is Nationally recognized day.
Please don’t confuse people. It may be your belief based on historical controversies that Christ was not born in December of our current calendar. Academically speaking it is controversial and there is evidence to be found on both sides of the argument. However Christians are celebrating Christ’s birth not his conception, regardless of when you believe that took place.
