Leap years are those years which are divisible by 4 EXCEPT for centuries when the century must be divisible by 400; they occur every four years (except possible when a century ends). 2000 IS divisible by 400 so it was a leap year. As 1980 was a leap year, by subtracting 1980 from the current year, dividing by 4 and ignoring any remainder, the number of leap years after 1980 is found. (2011 - 1980) ÷ 4 = 31 ÷ 4 = 7 r 3 → 7 leap years after 1980 → There were 8 leap years in 1980-2011, which were 1980, 1984, 1988, 1992, 1996, 2000, 2004, 2008 (These are also the years of the Summer Olympics.)
1976 1980 1984 1988 1992 1996 2000 2004 2008 2012
2064 − 1980 = 84 years
Including 2012 itself, there have been 20 leap years from 1933 to 2012. They were 1936, 1940, 1944, 1948, 1952, 1956, 1960, 1964, 1968, 1972, 1976, 1980, 1984, 1988, 1992, 1996, 2000, 2004, 2008 and 2012.
2012−2003 = 9 years
2012 - 1896 = 116 years.
789 years from 1223 to 2012
Since September 13, 1961, there have been 13 leap years. They were 1964, 1968, 1972, 1976, 1980, 1984, 1988, 1992, 1996, 2000, 2004, 2008 and 2012. The next leap year will be 2016.
