Never on Sunday rule

Like most people, I look forward to watching the Tournament of Roses Parade each New Years Day.  So, after a leisurely breakfast, a pot of coffee, taking up time with the dogs, I reached for the TV remote and turned on the channel guide to see which channel would carry the parade.

Duh!  It wasn't listed.

So I did a google search on the internet to find the right channel.  This year is it on Monday, January 2. I clicked on a "Never on Sunday" link and learned why it isn't today.  The parade goes back to the late 1800's.  It was agreed that it would never be held on a Sunday because it was feared the parade would disturb the horses tied up in front of churches along the route!!!  That rule still holds today.  I would guess it has lasted this long due to Sunday being designated as NFL coverage!  I note the college bowl games that are usually on New Years Day are also delayed until tomorrow.
