400 would have been a leap year.
The method for calculating leap years is a little complicated due to all the exceptions.
Years that are a multiple of 4 are a leap year, UNLESS the year is a multiple of 100 (then it is not a leap year), UNLESS the year is also a multiple of 400 (then it is a leap year).
Some examples
1800 - not a leap year because it is a multiple of 100
1900 - not a leap year because it is a multiple of 100
2000 - leap year because while it is a multiple of 100, it is also a multiple of 400
2100 - not a leap year because it is a multiple of 100
400 - leap year because while it is a multiple of 100, it is also a multiple of 400

Is 3000 a leap year?
No, 3000 is not a leap year. Leap years are divisible by 4, but if a year is divisible by 100, it is not a leap year unless it is also divisible by 400.
Whether there is any relation with 400 and 100 with a leap year as it has with 4 to determine?
There will be a leap year every 4 years except if it is divisible by 100. However, if it is also divisible by 400, it will be a leap year. 2000 was a leap year because it is divisible by 400, but 2100 will not be a leap year.
What is the probability that a year selected at random is a leap year with explanation?
The probability is very close to 0.25 A year is a leap year if the number is divisible by 4 - except if the number is divisible by 100 it is not a leap year - except if the number is divisible by 400 it is a leap year. So, in a 400-year period there are 97 leap years. The probability or relative frequency of leap years is, therefore, 97/400 = 0.2425
Is 2400 going to be a leap year a leap year?
Yes. It is divisible by 4 and by 400.
Was 1999 a leap year?
No it is not. A simple algorithm to check this is if the year is divisible by 4, but not by 100, then it is a leap year. Also if a year is divisible evenly by 400, then it is a leap year, but not all leap years are divisible by 400.
Why arnt there leap days in years ending in double zeros?
There can be. Years divisible by 100, but not by 400 are not leap years. So 1900 was not a leap year and 2100 will not be a leap year. The year 2000 was a leap year, because it was divisible by 400. So some double zero years can be a leap year. The next will be 2400.
Why century year should be divided by 400?
Because, if the year is divisible by 400, then it is a leap year.
What have you learned about a leap year?
1.Every 100th year which is divisible by both 100 and 400 is leap year. Eg: 2000 is divisible by both 100 and 400. so it is leap year. But 2100 is only divisible by 100 and not by 400. therefore it is not a leap year. 2.The year other than 100 which is divisible by 4 is leap year. Eg: 2004 is divisible by 4 but not 2005.
Why 1600 is not a leap year?
1600 is a leap year because 1600 is evenly divisible by 400.
A leap year is a year that is divisible by 400 or 4 but not 100 is 1600 a leap year?
Well if 1600 being divisible by 100 disqualified it as a leap year, that would contradict the rule that 400 is a leap year. So maybe a more explicit way to state the leap year rule would be: Is_Leap(year) = true: if 4 divides year OR 400 divides year false: All other cases. Hope this helps!
Why is 1900 not a leap year?
In the Gregorian calendar, for a year to be a leap year, the year would have to be not only divisible by 4, but in the cases where the year is divisible by 100, to be divisible by 400, also. Therefore, 2000 was a leap year, but 2100, 2200, 2300 will not be leap years.
Is 700 ad a leap year?
700 AD was not a leap year. It is divisible by 4 and by 100, but not by 400.
