Last night, while sitting outside - and helping hand out candy to all of the 'treeters who came up, my new mother-in-law was discussing how her sister and husband were going to their church for the Fall Harvest Festival.
I said... "What's that?"
She said, "Oh. It's like trick-or-treat - but they don't go door-to-door."
I asked, "Do they wear costumes?"
She said, "Oh yes! But not ghosts or monsters or other scary ones."
I said, "Oh. So... it's Halloween... but called something else."
She said, "Yes. Pretty much."
I said, "Oh. Sorta like buying a turkey around Thanksgiving, and fixing it and eating on Thanksgiving Day - but it's not celebrating Thanksgiving. I understand."
...so JWs aren't the only ones who twist things and make things suit their own peculiar beliefs.
Here is a link to something that explains it better... and sounds eerily familiar.
