Does anyone know how many seconds there are in a leap year?

31,556,926 seconds in a regular year, so I guess there'd be 31,643,326 in a leap year.
(86,400 seconds in a day)

That of course is a calendar year. YOu also have sidereal years, draconic year, galactic year, etc...

I came up with a differerent answer not quite that high. It seems like it would be simple but everyone comes up with a different answer, I guess because of the leap year factor.

I get 31,622,401, allowing for the leap second added to 2008.

Mike I didn't consider that extra second, your answer was closer to what I came up with though.

60(seconds in a minute)x60(minutes in an hour)x24(hours in a day)x366(days in a leap year)+1(extra leap second) = 31,622,401

Leap seconds a are different beast than leap years, despite sharing a similar name.

Interwebz wrote: The International Earth Rotation and Reference Systems Service (IERS) announces the insertion of a leap second whenever the difference between UTC and UT1 approaches 0.6 s, to keep the difference between UTC and UT1 from exceeding ±0.9 s. The announcement appears in IERS "Bulletin C", typically published every six months.

I also get 31,622,401 if you add the leap second. That is 60 seconds in a minute X 60 minutes in an hour X 24 hours in a day = 86,400. Then multiply that X 366 days = 31,622,400 + 1 leap second = 31,622,401.

The correct answer is twelve, and I got it from my eight year old grandson. He asked me the same question and I ciphered on it for awhile on it with the calculator too, only to learn the 'real' answer: Jan Second, Feb Second, March Second, Apr Second, May Second, etc.

Nope, sorry you are still wrong. Figuring that way, it is 24. He forgot January 22 (twenty-second), February 22 (twenty second), ..... LOL

Should figured there was a catch there. :lol:
