There were. 1972 and 1976 were intercalary years (leap years), as was 1980. Such years are sometimes called bissextile years.
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.
1980 was a leap year - therefore there were 366 days in 1980.
Yes. 1980 is divisible by 4, therefore it is a leap year (but note that there are exceptions to this rule at the end of a century).Yes. 1980 is divisible by 4, therefore it is a leap year (but note that there are exceptions to this rule at the end of a century).Yes. 1980 is divisible by 4, therefore it is a leap year (but note that there are exceptions to this rule at the end of a century).Yes. 1980 is divisible by 4, therefore it is a leap year (but note that there are exceptions to this rule at the end of a century).
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.)
366 - it was a leap year.
1 day :)
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.
Nope. But 1984 and 1988 were both leap years.
yes in fact the 19th leap year of the 20th century
There are 4 years between every leap year. Correction: There are 4 years between MOST leap years. That's the case 99.25% of the time. For the other 0.75% of the time, there are 8 years between leap years.
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.)
