The olympics don't take only one day, the paralympics are also a thing, as are the winter olympics. The olympics that happen on leap years are the summer olympics and February isn't in summer.
Early voting takes longer than a day, and there are elections other than presidential elections that happen with greater frequency.
And February 29 doesn't happen on years ending in 00 unless the year ends in 000.
EDIT: scroll down to see how confidently wrong I was about leap years!
To add to this, weather conditions on November 5 are likely to be more temperate than February 29. November 5 can definitely still have bad weather, but you would be making in-person voting overall objectively statistically more difficult by pushing it into the end of February thanks to snow, where November doesn't even crack the top 5 months for the most snowfall (and we're talking early November here).
You would also be giving some president/Congress three-ish extra months nine-ish fewer months of a term for literally no reason by shifting it all the way to February 29, unless you wanted to roll out some decades-long scheme to incrementally push it there.
Edit: that also leaves the fact that you would have (presumably the first day of) one of the most watched events on Earth taking place on the same day as the general election, meaning arguably one of the few times when minute-by-minute 24-hour news coverage is necessary for the election, you'd get it interspersed with a ton of Olympics stuff, and you'd likely also have a decent chunk of people staying home to watch the Olympics instead of voting, further depressing turnout in addition to possible weather issues.
In 2000, there was a February 29, because it was a multiple of 4, and despite being a multiple of 100 it was also a multiple of 400. It was the exception of the exception of the exception. My parents signed their divorce on that day. Which makes it extra memorable for me. What a day 😀 !!
To me the most baffling thing is that it's not on the weekend in the USA AFAIK, like why the fuck would you have it on say a Tuesday when people need to work, pick up their kids from school etc, you might argue that still some people work on the weekends but that's a much lesser percentage and makes voting easier for a lot of people and who does have to work, they can mail it in.
Pretty sure my polling place is open for more than 12 hours. Maybe it varies by state, but that should be a reasonable amount of time for over 99% of the population to get there. Obviously, some places are massively overrun and understaffed, especially in the "unfavorable" districts, but I've had no issues making it out in less than 10 minutes by leaving for work 20 minutes early.
Is literally every business closed all weekend where you live? Or is this just another case of people not realizing that lots of people work holidays and weekends?
Businesses are already legally required to let people leave to vote.
At the time most Americans were farmers. Can't be Sunday because it's a Christian rest day, Wednesday neither because that's market day. They might have to travel a whole day to get there, so it can't be on Monday or Thursday either. Which leaves only Tuesday, Friday and Saturday.
Not quite—it’s every four years, excluding years divisible by 100, but not excluding years divisible by 400. So 2000 was a leap year, but it was the first century in 400 years for which that was the case (using the Gregorian calendar).
