urban myth?

I've studied many different backgrounds to the date of December 25th.

It was the date decided upon by the Roman catholic church in an attempt to counter an evil holiday being celebrated.

There are many arguments about Christ not being born in their wintertime because of the verse about Shepherds watching their flocks by night. However, in that area, sheep are still herded there and though winters might be cold, not so cold that shepherds are not out watching their flocks.
