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.

(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.)
As of 2015, the leap years since 1980 were 1980 itself, 1984, 1988, 1992, 1996, 2000, 2004, 2008 and 2012. 2016 is the next one.
The leap year immediately before 1980 was 1976.

(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.)
Including 1980, there are 9 leap years between 1980 and 2014. They are 1980, 1984, 1988, 1992, 1996, 2000, 2004, 2008 and 2012.
As of 2011, the leap years since 1974 have fallen in the following years: 1976 1980 1984 1988 1992 1996 2000 2004 2008 The next leap year will fall in 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.
1980 was a leap year - therefore there were 366 days in 1980.
There were 5 years between 1977 and 1998. They were 1980, 1984, 1988, 1992, and 1996.
366 - it was a leap year.
There were 15 leap years in that period. They were 1952, 1956, 1960, 1964, 1968, 1972, 1976, 1980, 1984, 1988, 1992, 1996, 2000, 2004 and 2008.
16 leap years
The leap years since 1952 have been: 1952 1956 1960 1964 1968 1972 1976 1980 1984 1988 1992 1996 2000 2004 2008 The next leap year will fall in 2012.
24 leap years
