It’s no secret that Christmas falls during the month of December.
What isn’t as clear is the reason why.
“That’s easy,” one might reply. “It’s when Jesus was born.”
Actually, it wasn’t.
Most biblical historians place Jesus’s birth around either October(ish) or April(ish). They argue that shepherds would not have been out in the fields with their sheep in the dead of winter. It would have been far too cold, especially at night. (Fun fact: Christ likely wasn’t born in the year 0 AD either. Because of some miscalculations in the Gregorian calendar, he was probably born sometime between 3 to 5 BC.)
Secularists–and particularly militant atheists–enjoy rubbing that little detail into the face of unsuspecting Christians before adding, with gleeful snark, that the whole Christmas holiday is based on a pagan holiday filled with drunken debauchery, which is true.
