Therefore, the

**year**2000 will be a**leap year**, but the**years**1700, 1800, and 1900 were not. The complete list of**leap years**in the first half of the**21st century**is therefore 2000, 2004, 2008, 2012, 2016, 2020, 2024, 2028, 2032, 2036, 2040, 2044, and 2048.Keeping this in view, how many leap years has it been since 1968?

1904, 1908, 1912, 1916, 1920, 1924, 1928, 1932, 1936, 1940, 1944, 1948, 1952, 1956, 1960, 1964,

**1968**, 1972, 1976, 1980, 1984, 1988, 1992, 1996, 2000, 2004, 2008, 2012, 2016, 2020.When was our last leap year?

**2016**is a leap year, which means that it has 366 days instead of the usual 365 days that an ordinary year has. An extra day is added in a leap year—

**February 29**—which is called an intercalary day or a leap day.

Is there a leap year every 4 years?

A common

**year**has 365 days and a**leap year**366 days, with the extra--or intercalary--day designated as February 29. A**leap year**occurs**every four years**to help synchronize the calendar**year**with the solar**year**, or the length of time it takes the earth to complete its orbit around the sun, which is about 365Â¼ days.
