A Leap Year occurs every four years unless it is divisible by 100. Those years are not Leap Years unless they are also divisible by 400. That is why in the chart above 1900, 2100, 2200, 2300 are not Leap Years but 2000 and 2400 are Leap Years.
I had my students write computer programs to figure out leap years, the day of the week given the date, the date of Easter, etc.
Here is the algorithm as it would appear in the computer program for finding whether a year is a Leap Year:
if year is divisible by 400 then leap year is true
else if year is divisible by 100 then leap year is false
else if year is divisible by 4 then leap year is true
else leap year is false
