Yes indeed, which is precisely why we celebrate Christmas on a date that so close to that of the winter solstice. So for all of those secular "Season Greetings" types, there's nothing wrong with saying "Merry Christmas," since the date itself doesn't have any religious significance and most likely was picked to coincide with the shortest day of the year.
