Part of the overkill is due to the retail industry. No sooner is Black Friday over, the Christmas trees and lights are up, gotta get the space ready for Santa’s workshop, all that deal.
Even at Macy’s Thanksgiving Day Parade, the last float is Santy Claus.
The turkey is still in the oven and we’re barreling down on Christmas.
At least some Christians keep their trees and mangers up through Epiphany (January 5). Others take Christmas down the day after.
I prefer to keep Christmas up a little longer. January is a long, cold, dark month.
