Depends on if they have extra magic hours and what time of year it is. Right now I think its between 12 and 1 AM, and you can also have extra magic if your at a resort till later.
11 pm
Magic Kingdom closes at 11pm on Saturdays
It closes at midnight on Saturday
11pm or 9pm
11:00PM
If you have extra magic hours it is 11:00PM normally it's 9:00 PM
