I was wondering if anyone has a simple explanation/formula for how to determine whether or not a calendar year is in fact a leap-year.

The reason I ask is because I have a Business Math final exam tomorrow, and we'll likely be using leap-years in a few problems. I've looked on some sites, but they only explain the history and ideas behind the leap-year.

Isn't it every four years....
normal year= 365 days
leap year = 366 days

that'd be slightly creepy if i didn't find it so amusing.
Divisible evenly by 4.
Ie 2000,2004,2008,2012,1996, etc.

I can fap to this. Keep going.
yah every year is actually 365.25 days, so if the last 2 digits are divisible by 4 (including 00), it's a leap year

That pretty much ends the thread right there.

ಠ_ಠ

wat

It happens every 4 years because the earth's orbit of the sun isnt exactly 365 days, its closer to 365 1/4, so every four years they add a day to make up for it.

No it doesn't, because that's wrong.

Every year divisible by 4, except those divisible by 100 but not 400. So every fourth year except for 1700, 1800, 1900, 2100, 2200 etc. But 1600, 2000, 2400 are leap years.

That's all there is to it.

Thank you for clearing that up, that's some of the basis of the confusion I was having...not the fact that there are 366 days, or that it happens every 4 years.

Come on guys, I'm not THAT much of a lost cause.
here's another question

what if you were born on a leap day?

Then you are one of the few who can say their birthday is February 29th, and that intrigues people.

That's pretty much it.
For those in the US it's every presidential election year.

Edit: For the rest of the world it's the same year as the summer olympics.
