How much longer is Halloween event going on?

The post in the news section says Nov. 4th but I still see halloween hued mobs. How long has it been extended for? Thanks.

Yes, this sunday we will do an invasion or two and do some harrowers or something nice.
Has any of this happened yet or are approximate timetables available? I don't have much time today but would love to squeeze out an hour or two for Uof if I knew when.
