Last year the Disney Parks Blog officially announced the dates on May 8th.
But you can look at the current September and October travel agent calendars and make initial guess when the parties will be. Any night MK closes at 7pm is expected to be a party night.
The exception is September 5 and 6, which is for Night of Joy.
