Planning our trip in June I just checked the Magic Kingdom closing times they close a lot of days in February at 1 AM

With EMH one day they close at 3 AM is this correct?

In June all the days were there they close at 10 PM

Except for one EMH night they close at midnight

What am I missing? Wouldn't it be better to close later in the summer when it's hotter and it's more crowded?

It's been about seven years since I've been to Disney World so There's a lot of new stuff and a lot of stuff that I have forgotten.
