If you honestly spend 6 months of the year planning one day, you seriously need to get a grip.
But it's not one day is it yellow? It's the build up, the budgeting, the gift buying that often needs to be spread over several months to be economical... I love Christmas and I never ever think of it as ONE DAY.
And OP YABU, just hide it, nobody's forcing you to read it or agree.
