Extended Hours In Sept 2007

[ACJT]

I know park hours won't be out for a while for Sept, but is there a general rule of thumb which night of the week that Magic Kingdom, Epcot, and MGM have extended evening hours?? i.e. epcot always has their extended evening hours on Tues??

Magic Kingdom tends to have evening EMH on Sunday, Epcot tends to have evening EMH on Friday, and the Studios tend to have evening EMH on Monday.
