That's ture, and of course that was why Saturnalia was held at that time.<quoted text>
Actually it is because of the Winter Solstice more than anything else.
Just as spring and Easter is the spring equinox.
Until the 325 Council of Nicea Easter was celebrated on the Sunday after the first full moon following the vernal equinox.

And SHHH! Don't confuse our latest batch with the facts.
