I don't know, and don't particularly care, how many seconds are in a leap year. My question is, how much time was wasted, adding up the seconds, posting it on line, multiplied by the time it took, all of the viewers to read it? :biggrinjester:

As a forum member with a degree in mathematics, I find this to be the simplest answer: http://bfy.tw/LLnP

But Sodbuster’s grandson has a more elegant solution.

Without reading through it all- remember that every year is actually 365.25 days, and that is why we have leap year, which adds a day on the 4th year to keep us on track. Otherwise over time, our seasons would change, among other things.

A thread necromancy after NINE YEARS has to be some kind of a record. How many seconds is THAT?

What was your answer and how did you get it? Be sure to show your work for full credit :rules: :smilelol5:
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.
"rlol"

And add me to the 31,622,400 crowd. Leap seconds have nothing to do with leap years.

Seconds in a leap year is easy.

How many in a non-leap year is more interesting.
Is it 31,556,925 or 31,556,925.1, or 31,536,000?

Neither. You have to start with how many seconds are in a day? Is it 86164.1 or 86,400?

According to the United States Naval Observatory (the go to for all things time related): "That is, the length of the mean solar day is at present about 86,400.002 seconds instead of exactly 86,400 seconds."

Not quite true; it's trivia time. Every year is actually 365.2425 days. Leap year is every year divisible by 4, except years that are divisible 100, unless it is divisible by 400. So what does that mean? 1700, 1800, & 1900 were not leap years, now 2000 was (probably why most don't know about this rule), and 2100, 2200, & 2300 will not be leap years.

:lol: :iagree:

It really gets messy when you realize that, while time is a constant, the way we count it according to the Earth's obit and rotation is inaccurate due to irregularities of our solar orbit and that our own spin is slowing down and even that can be and is effected by large seismic events.
