Park Operating Hours

[WDW Mad4Mickey]

How many months in advance does Disney confirm park and fireworks schedule?

 

[Robo]

Over 6 months in advance.
However, they modify those hours during the last 10-45 days before the actual dates.

The early releases are rarely the final version. Usually, you will get a better idea of the final schedule by looking at the calendar for the same days the previous year. Most times are finalized about a month out, but occasionally big changes are made a week or two out and extended hours announcements are sometimes made same-day.
