For those curious, the Palestinian winters would be too cold for shepards to be watching their flocks at night and the Romans would never hold a census in winter. Jesus was likely born in Summer time.
Also, Christmas comes from the combination of pagan holidays and traditions, mainly revolving around the celebration of the return of sunlight as the days began to grow longer after being so short for so long. The main theory behind why Christmas came to be celebrated in winter is combination of Christians hiding from Rome by celebrating around the Winter Solstice, and England using the "return of light to the world" as a holiday symbol.
Great history lesson as always, Bob. You are a well read and intriguing fellow.
My favorite holiday movies are A Christmas Story and Goodfellas
