uhh.... yes it was....

and if I'm wrong,

why wasn't it?

and if I'm wrong,

why wasn't it?

Only every 00 year is a leap year. That's why 2000 was and 1700, 1800 and 1900 weren't.

Sorry, every 4th 00 year.

excuse me, 1900 was a leap year! I should know since I happen to be born February 29, 1900!

James wouldn't celebrate his birthday. The average life expectancy is 73. So ure wrong.

pizza head what are you talking about? if a leap year happens every 4 years and there are exactly 25x4 years between 1900 and 2000 if 2000 was a leap year (which it was) then so was 1900. if you want to find out if a year is a leap year if the year say 1900 divides by four with no remainders it is! ie. 1900/4=475 +no remainders, therefore a leap year!

Actually, pizzahead is right. see this link: www.rog.nmm.ac.uk/leaflets/leapyear/leapyear.html

it states that if the year is a '00' year, then it must be divisible by 400 to be a leap year. Therefore, 2000 is, whereas 1900 is not.

1900 is a leap year. go to a calculator and put in 2000 and keep subtracting 4. eventually you will get to 1900.

Melody, check out the link i posted; 1900 is NOT a leap year... "The discrepancy between the actual length of the year, 365.24219 days, and the adopted length, 365.25 days, may not seem important but over hundreds of years the difference becomes obvious. The reason for this is that the seasons, which depend on the date in the tropical year, were getting progressively out of kilter with the calendar date.

The change from the Julian calendar to the Gregorian [in 1582] involved the change of the simple rule for leap-years to the more complex one in which century years should only be leap-years if they were divisible by 400. For example, 1700, 1800 and 1900 are not leap-years whereas 2000 will be. "

bluetwo sorry that makes no sense to me. I know why we have leap years but there's one every 4 years because there are 365 1/4 days in a year. 1/4 x 4 is 1. The link didn't make sense.

sorry, my mistake. it took some thinking, but now it makes sense.

Awww.... maybe James wasnt lying, maybe he was just confused... hehe... cut the boy some slack

The leap year rule is three-pronged. (1) If a year is divisible by four it is a leap year, but (2) if is divisible by 100, it is not a leap year, but (3) if it is divisible by 400 it is a leap year. So 1900 isn't a leap year (divisible by 100), while 2000 is (divisible by 400). Those last two conditions only kick in every 100 or 400 years.

To each his own opinion!!!

I personally think that it WAS a leap year, but TO EACH HIS OWN ALREADY!!!

People, who cares if it was a leap year or not? Instead of fighting, just go find another teaser to read.

Probably more of a debate than a fight. Sorry.

i think he will be dead by then ONLY if he was a ghost and if he was than u are a ghost buster and if you were then write me an e-mail and tell me how you pass ur days with them

Huh? 1900/4=475. 1900 IS a leap year.

Snaps is wrong. Yes, leap years are divisible by 4, AS IS 100!

question mark - let me tell you the *only* thing i remember learning in year 9 maths was that for a year which ends in a 00 (ie, 100, 200 ... 1900, 2000, etc) to be a leap year, it must be divisible by 400. if it ends in something *other* than a 00, (eg, 12, 19, 45 etc) then it only needs to be divisible by 4...

Why is theres so much debate over a fact? There is no "opinion". The answer is correct. By the rules of the Gregorian Calendar, 1900 is not a leap year. What makes this teaser tricky is that some people do not realize this fact, thinking that all years that are divisible by 4 are leap years.

I DON"T GET IT IT IS MIGHTY STUPID

1900 WAS NOT A LEAP YEAR! This is a true fact! Do not just say 'no that's wrong' without verifying it! For example, Wikipedia states the same thing that many have said, only centuries divisible by 400 are leap years. Ignorance is no excuse for saying someone is wrong about something that is clearly a fact! So please, no more argument, it can be easily verified (assuming you're smart enough to use a search engine) that 1900 is NOT a leap year. End of discussion.

It has to be a leap year

if 1992 was a leap year(when I was born)then 2000 is a leap year. now count back.

Easier way is this

4*25=100

2000-100=1900

so why cant it be a leap year

4*25=100

2000-100=1900

so why cant it be a leap year

If 2000 is a leap year (which is commonly accepted), then 1996 was one, and 1992, 1988, 1984, 1980, 1976, 1972, 1968, 1964, 1960, 1956, 1952, 1948, 1944, 1940, 1936, 1932, 1928, 1924, 1920, 1916, 1912, 1908, 1904, and 1900 were all leap years too. I'm really confused.

This is really confusing. . . . I thought it was a leap year.

well I think it is AND it isn't... hope that helps

lol j/k -- all I know is I got it wrong.

would he have even lived to 100 anyway?

lots of people have lived to 100.

From wikipedia:

ear 1900 (MCM) was an exceptional common year starting on Monday of the Gregorian calendar, but a leap year starting on Saturday of the Julian calendar.

Oops. xP

Year, not ear.

Year, not ear.

This is the method for determining a leap year. Don't think about this in any other terms.

To determine whether a year is a leap year, follow these steps:

1.If the year is evenly divisible by 4, go to step 2. Otherwise, go to step 5.

2.If the year is evenly divisible by 100, go to step 3. Otherwise, go to step 4.

3.If the year is evenly divisible by 400, go to step 4. Otherwise, go to step 5.

4.The year is a leap year (it has 366 days).

5.The year is not a leap year (it has 365 days).
