FEA Sparkling Dessert Party Days

Is there any consistency or method on what days of the week Disney has the FEA Sparkling Dessert Party? I believe the actual dates are usually released 60-90 days beforehand but I am trying to determine what days I want to do which parks. I am going the last week of November and would like to do Epcot on Wednesday and Saturday but we are really wanting to do this dessert party. Any thoughts or insight is greatly appreciated!

They don’t do it on an Epcot EMH evening, I noted. (Which does make sense.)

Thanks! That does help.
