Leap years have an extra day in February, so there are 29 days in February and 366 days in a leap year. Lots of people believe that if a year is divisible by 4 it is a leap year. However there are some exceptions to this.

To work it out follow these instructions.

 
If the year divides exactly by 4 it is a leap year, UNLESS
it is a new century. (ends in 00)
If this is the case if it divides exactly by 400 it is a leap year, if not it is not.
 
Examples
 
Was 2012 a leap year?
2012÷4 = 503. YES!
 
Will 2018 be a leap year?
2018÷4 = 504 r2 NO!
 
Was 2000 a leap year?
2000÷400 = 5 YES!
 
Will 2100 be a leap year?
2100÷400 = 5 r100 NO!
