How many leap years are there from 1776 to 1976?

Answer 1

As of and including 2012, there have been twelve leap years since 1966.

Simply taking the number of elapsed years and dividing by four will only get you the correct answer part of the time, since it mathematically assumes the year before you start counting is a leap year.

Answer 2

From 1776 to 1975 (inclusive) is 200 years. There are leap years every four years, in year numbers that are divisible by four, EXCEPT century years. Year numbers that are divisible by 100 are NOT leap years.

So out of 200 years, there should be 50 leap years, minus 2 for 1800 and 1900.

Then add in 1976, and we come up with 49 leap years between 1776 and 1976, inclusive.

There is one additional exception; century years such as 1800 and 1900 are not leap years, EXCEPT that year numbers divisible by 400 ARE leap years. So 2000 was a leap year.

Answer 3

There are 49 leap years between 1776 and 1976. Leap years occur every 4 years, except for years that are divisible by 100 but not by 400.
