Christmas is a season, and it does not begin until Christmas Day proper. The Church celebrates Christmas over eight days, or an Octave. The period before Christmas is not part of Christmas season, it is a separate season known as Advent. Yesterday, the first Sunday after Christmas Day, was the Feast of the Holy Family.
And if none of that interests you or even bothers you, you may focus on Foghorn Leghorn, Snoopy, or the M&M character. Christmas can handle it all.
