October 31, though many communities organize local events for weekend nights before Halloween.

Halloween happens on Halloween.

Monday. Neighborhood participation varies wildly block to block though. Little kids usually come around earliest with the big kids without costumes going as late as 9pm or so.

Thanks all! I did try Google but gave up the ghost after page 4.

It always happens on Halloween. No need to Google this.

Maybe in Baltimore. Not true everywhere - one example from last year: https://www.charlestonwv.gov/news-items/thu-09232021-1044/trick-or-treat-2021. It’s very common in other places for trick or treat to not be on October 31.

Then when do they having moving night?

Yeah I'm curious if the kids are going to come out on Sunday night (10/30) or Monday the actual Halloween day or both???

Amazing how many people still can't figure this out.

that's a regional thing.

i side-eye any government entity trying to change a very basic holiday like Halloween.

Monday.

Didn’t ask about Halloween. I asked about trick or treat. Many places have trick or treat on days other than Halloween; it varies every year.
