How far in advance do you know EMH for the parks?

We will be there Thanksgiving week and I am wondering how far out do they announce the EMH for each park? What about the operating hours for the parks and any special events to be aware of to void planning to visit those parks?

You should have a good idea of them about 6-7 months out. “Final” park hours are usually released on the 15th of the month prior. Tweaks can/will be made as necessary.
