Interesting that there are dates late November and the beginning of December from 4 to 10 on Saturdays and 5 to 10 on Friday and Sundays. Nothing mid November and closer to Christmas. 

Winterfest gone?

 

Edited to add: Forth of July closes at 10.  No 11p closes that I can see, 12a for October. 

There's probably some sort of limitation with the website where they can't post hours more than a year out. Magic Mountain also has their hours posted only to one year out from this week. They're definitely not trying to do "normal" operating days that late in November (especially with what a flop the "bonus" weekend was and how cold it's been this year), and it's not like they'd only do two weeks of Winterfest.

I did just see on Facebook that they are "actively working" on the site that's showing limited December dates. 

Other than that, hours still kind of sad 10 pm closure on 4th of July and the lack of 11 pm closes.

I bet those parts of the calendar (like July 4) might be released with the events schedule. With the park already putting out the America 250 merch I could see them having a longer Independence Day celebration than normal as well.
