Nighttime shows during December - what and when?

I am going to WDW on December 16-26. When do they change from the Main Street Electrical Parade to the Christmas parade, Wishes to Christmas Wishes, etc? I’m trying to figure out if I can see all the different shows while I am there.

Also, do they still have the Electrical Water Pageant throughout the whole month of December?

Thank you for all your help.
