Radio  

Somebody added the following comment to the article, which somebody else recently deleted:
(Could someone comment on the situation where most radio stations stop playing Christmas music when Christmas day is past? There was a 1-day extension of playing Christmas music in 2004, when Christmas day was a Saturday. It is still Christmas time the day after Christmas day, with Epiphany being 12 days after Christmas day.)
I pasted it here for discussion, if anybody is interested.  I added a couple of section heads above, too.  
My thoughts regarding the question are that the pre-Christmas hoopla has been so extended, starting before Halloween now, that people who are not thinking about the liturgical calendar are glad that it's over.
