If there is a war on Christmas, Christmas is winning.

Every year, there’s a chorus of complaints that Christmas is underappreciated and even under attack. There was the flap about the red-and-green Starbucks cup, and Donald Trump told voters that he supports saying “Merry Christmas” over “Happy Holidays.” The evidence suggests Christmas is still going strong.

One good measure of the season is holiday music. O.K., Christmas music. Some radio stations begin switching formats to wall-to-wall Christmas music as early as Nov. 2, just a few days after Halloween. Nearly two-thirds of the stations that switch have done so by the day before Thanksgiving, according to Nielsen, which tracks these sorts of things.

And don’t think for a moment that the religious-music stations are the traditionalists that want to keep Christmas special. A third of those switch well before Thanksgiving. (Nielsen Music says 171 of the 1,574 American radio stations it monitors switched to an “All Holiday Music” format.)
