Park hours question

We will be visiting in February during the busy Presidents Day week. I will be making my FP ressies in a few weeks and am still trying to figure out which park to visit on which days. My question is how far in advance does Disney adjust park hours? When I look at the hours for that week (supposedly one of the busier weeks of the year), it says that MK closes at 8pm all week. I was expecting 10pm or 11pm closings. Will they adjust these before I have to make my FP ressies? I can't imagine an 8pm closing for that week. Thanks

Disney can make tweaks to park hours right up to the very day the park is to open. I would suspect the parks will be open later during Presidents' Day week but am not sure when Disney might post updated schedules.

We were there last year around that time and hours were not extended until very close to our travel dates. Its very frustrating! Disney expects guests to make plans starting 180 days out, but hours are very sketchy until around 30 days or less out.
