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).
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.
(1990 - 1980) ÷ 4 = 10 ÷ 4 = 2 r 2 → 2 leap years after 1980
→ There were 3 leap years in 1980-1990, which were 1980, 1984, 1988.
(These are also the years of the Summer Olympics.)

2064 − 1980 = 84 years
1990 to 2014 is 24 years, not 22 years.
Calculated from 2010, the year of birth was 1980. (2010 minus 30 = 1980).
2012 -1990 =22
It is 36 years.
I first answered this question in August 2010. It is now January 2018, so I'll update it: Not sure if you're wanting 1980 included or not since it was a leap year. 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. (2018 - 1980) ÷ 4 = 38 ÷ 4 = 9 r 2 → 9 leap years after 1980 Including 1980 there have been 10 leap years: 1980, 1984, 1988, 1992, 1996, 2000, 2004, 2008, 2012, 2016 Excluding 1980, the first leap year after 1980 was 1984 there have been 9. The next leap years will be 2020, 2024, 2028, 2032, ... These are the years of the Summer Olympic games.
34 years.
32 years
There have been many = 1980, 1988, 1990 . 1993 , 2003
32 years.
As of September 2014, the year 1990 was 24 years ago. if you subtract 1990 from the present year, you will find your answer. 2014 - 1990 = 14
