Holiday Storytellers schedule?

[sheila <3 WDW]

Planning my first Christmas trip! I was looking at historical showtimes online and noticed the storytellers at Epcot tended to have the same schedule every day.
Is this typically announced in advance like parades and fireworks or will I have to wait and see what the times guide says?
Thanks!

Sorry, this should have been in Theme Parks.
