how to calculate a leap year ? is 2000 is a leap yr?why 3000 is not a leap yr?

Answer 1

3000 is not a leap yer as it is not divisible by 4 and 2000 is a leap tear as it is divisible by 4

Answer 2

Why is the year 3000 not a leap year? Well, just as there are leap years, there are such things as LEAP CENTURIES . and every 400 years or so we skip the leap Century to compensate for correcting our calendars.. And then there is something known as a LEAP MILLENIUM. I know this is a bit complex, but here is a website that can explain it better than I can (bear in mind this was published before the year 2000 )

The year 2000 is approaching and bringing with it many questions. One question some may ask, "Is it going to be leap year?"

As a matter of fact, it will be a leap year, but there is a lot more to the story. Here's the rest of the story.

As the earth travels in its orbit completely around the sun once each year it is also revolving approximately 365 times. But, as we reach that spot in the universe where the clock strikes mid-night on December 31, we are not quite as far along in the orbit as we should be.

Scientists have discovered that every four years or so we actually end up being about one day short of where we should be on our orbital path. Naturally, the best solution to get us caught up is to add an extra day to every fourth year. That's exactly what we do, and we add it to our shortest month, February. The years in which we add the extra day are known as Leap years. Normally February has 28 days, but on a leap year February has 29 days.

If you wish to calculate when a leap year will occur you are fairly sure to get it right if the year is divisible by four. (1904, 1908, etc.)

There's only one problem with this: We still don't end up exactly at the same spot in our orbit around the sun after a while because this method over-compensates for the error. To correct for this problem scientists have calculated that we need to "skip" a leap year every once-in-a-while. Every once-in-a-while is about every 100 years. So, at the turn of the century we normally skip a leap year to compensate. But, that tends to over-compensate, so, once every 400 years we DO NOT skip a leap year.

If a centenial year is not divisible by four, there will be NO leap year that year. For instance, 1200 was a leap year, 1600 was a leap year, 1900 was NOT a leap year . . .

The 400-year correction turns out to be another over-correction by just a few seconds. Therefore, whenever a millenium begins with an odd number (1000, 3000) scientists leave out an extra day and DO NOT make it a leap year.

But don't worry about it, as neither you nor I will be around in a century, or 400 years, much less the year 3,000 !

Answer 3

Was 2000 A Leap Year

Answer 4

Rules for determining when to have a leap year

In order to get a closer approximation, it was decided to have a leap day 97 years out of 400 rather than once every 4 years. To implement the model, it was provided that years divisible by 100 would be leap years only if they were divisible by 400 as well. So, in the last millennium, 1600 and 2000 were leap years, but 1700, 1800 and 1900 were not. In this millennium, 2100, 2200, 2300 and 2500 will not be leap years, but 2400 will be. The years that are divisible by 100 but not 400 are known as "exceptional common years". By this rule, the average number of days per year will be 365 + 1/4 - 1/100 + 1/400 = 365.2425.

Answer 5

Oh dear, this is small tricky logic behind this

Rule 1 : Every year which is divisble by 4 and not by 100 is leap year.

Rule 2 : Everyyear which is divisble by 100 and by 400 is a leap year in other words years divisible by 100 would be leap years only if they were divisible by 400 as well.

and hence year 1700 ,1800 ,1900 were not leap years so will be with 3000, but year 2000 is leap year.
I learnt this in grade 10 while writing a program in C for leap year logic.
you can get more info from below source about why is it like that

Answer 7

You need to divide the year with 4, no balance means it is a leap year, but if it's divisible by 100 it is not, then again if you can divide it with 400 it is

Therefore 2000 is a leap year but 3000 is not

2000/4 = 500
But 2000 can also be divided with 100 therefore it's not
Then again you can divide it with 400 so it is a leap year.

3000 is not divisible by 400 so it's not

Answer 8

A year is leap if it divides by 4. There is an exception though: years that divide by 100 but not 400 are not leap. Thus, 2000 is leap, but 3000 isn't leap, neither 2100 (according to the Gregorian calendar).

Answer 9

A leap year is NOT just any year that is divisible by 4, and 3000 will NOT be a leap year.

A year is a leap year if:
- it is divisible by 4, AND
- it is not divisible by 100, unless it is divisible by 400

So:
2004, 2008 are leap years (divisible by 4 but not by 100)
1900, 3000 are not leap years (divisible by 100 but not by 400)
2400, 3200 are leap years (divisble by 400)

An equivalent way to say it is that:
- If it is divisible by 400, it is a leap year.
- If it is divisible by 100 but not by 400, it is NOT a leap year.
- If it is divisible by 4 but not by 100, it is a leap year.
- If it is not divisible by 4 it is not a leap year.

I've noticed a couple of people below are saying that every 400 years we need to drop a leap year. This is incorrect. In every 400 years we need to drop approximately THREE leap years, which is why we drop 2100, 2200 and 2300 but not 2400.

Incidentally, someone said below that 1200 and 1600 were leap years. This is wrong; the Gregorian calendar wasn't even around in 1200.

Answer 10

LEAP year is the year in which there are 29 days in the month of Feb. and 366 days in a year.
The best way to find that an year is a leap year or not is to divide the by '4'.IF it is an perfect answer(natural number) then the year is a leap year.
For year 2000:: 2000/4 =500(natural no.)hence year2000 is a leap year.
year 3000 is also an leap year

Answer 11

Leap years are years that are divisible evenly by 4. .....2000 was a leap year but 3000 won't be because the millenia years have to be divisible evenly by 400.
