I've never seen it be moved. It's probably still Monday. I remember back when I was a kid, there was school the next day but my parents would let me stay up longer for that night. Back then trick or treating went up to around midnight. Now it seems there's nobody out past 8. Probably because of all the pedophiles and stuff. Back when I went the only thing we had to worry about is razor blades and poison, and it never happened. My mom would check all the candy to ensure it was not tampered with before I could eat any. Come to think of it, I never heard of anyone finding bad candy.
