Leap years are any years evenly divisible by four, with two exceptions. So years like 2004 and 2008 are leap years.
The two exceptions:
Any "century" year evenly divisible by 100 is NOT a leap year, so 1900 was not a leap year and 2100 will not be a leap year, except:
Any year number divisible by 400 IS a leap year, so 2000 was and 2400 will be leap years.
Of the 1000 years between 2001 and 3000, there are 250 "divisible by 4" years, minus 10 "century" years plus 2 "divisible by 400" years (2400 and 2800) gives 242 leap years between 2001 and 3000. Add 2000, and there are 243 leap years between 2000 and 3000, inclusive.

Leap Years are years divisible by four, with two exceptions. 1. "Century" year numbers (divisible evenly by 100) are not leap years. 2. Years divisible evenly by 400 ARE leap years. So years like 1992 and 1996 were leap years. Century years like 1900 or 2100 are NOT leap years. But 2000 was a leap year, and 2400 will be.
The leap years from 2000 to 2099 are:2000200420082012201620202024202820322036204020442048205220562060206420682072207620802084208820922096
That is correct. The leap years from 1950 to 1970 were:196019641968
Any planet with people who use calendars would need to invent leap years.
In non-leap years, February has 28 days. 28 is a multiple of 4.
