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.
1950 was a non-leap year which began on a Sunday, so 24th May was a Wednesday.
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.
Any planet with people who use calendars would need to invent leap years.
The duration of a solar year is slightly less than 365.25 days. Over a period of four centuries, the accumulated error of adding a leap day every four years amounts to about three extra days. The Gregorian Calendar therefore omits 3 leap days every 400 years, omitting February 29 in the 3 century years (integer multiples of 100) that are not also integer multiples of 400. (not 4)
There were 10 leap years between 1970 and 2011.
There were. 1972 and 1976 were intercalary years (leap years), as was 1980. Such years are sometimes called bissextile years.
1,576,800 if there are no leap years. If one of the 3 years is a leap year then it is 1,578,240 minutes.
Here they are:190419081912191619201924192819321936194019441948
1972 was the only leap year between 1969 and 1975.
It did not fit the rules to be a leap year. Leap years are evenly divisible by 4, they are also evenly divisible by 100 but NOT evenly divisible by 400. 1974 is not evenly divisible by 4. 1972 and 1976 were leap years. It is usually only every second even year that is a leap year. So 1970, 1974 and 1978 were not leap years, but 1972, 1976 and 1980 were leap years.
There are 1095 days in three years but if there was a leap year in those three years there will be 1096 days.
The odds are 91% that any given 12-year period will include three leap years. The other 9% of the time there are two leap years in a 12-year period. There are never four leap years in a 12-year period.

There were two leap years from 1999 to 2009: 2000 and 2004. Leap years occur every four years to account for the extra 0.25 days in a solar year.
There were 20 leap years from 1929 through 2008. (the next one is 2012):19321936194019441948195219561960196419681972197619801984198819921996200020042008
1950 Calendar year is exactly the same as 1961, 1967, 1978, 1989, 1995, 2006, 2017, 2023, 2034, 2045. As 1950 was not a leap year, none of these are leap years. http://www.jimloy.com/math/day-week.htm has the calculation method I used.
