Taking on the holiday calendar

I've said this a thousand times but on Halloween it bears repeating. I cannot think of one reason we should not celebrate this holiday on a weekend. I know there are some weird religious reasons to keep it on the 31st but like Mormonism and that weird Kabalah thing, can't we just ignore it?? There are a ton of holidays we do not celebrate on their actual proper day (MLK birthday, president's day), there are also a ton of holidays already set to fall on a specific weekend (Thanksgiving, Labor Day) and we aren't even consistent with ones with a religious basis (Christ's birth has an actual date while his resurrection is forty days after a Wednesday in April). Did they write one day down on the ancient calendar but not the other??
This IS supposed to be the ultimate kid's holiday yet 4 out of 7 years it will fall on a normal weekday (I am OK with Friday) which makes it inconvenient for parents, a distraction for schools and not all that great for kids. Celebrate it on the last Saturday in October which would allow for a full day of parties, trick or treating and fun. This would allow school to celebrate it on Friday prolonging the fun a bit and allow a kid to be in bed at a normal hour not going door to door for a sugar fix until 11pm on a school night.

If nothing else you're much more likely to get a bunch of hot chicks to slut out on a Saturday night when they can leave from home and party all night then some cold Monday when they have to be at work.
