Pedantic but this drives me nuts - this algorithm has to do 3 divisions for almost every year. If you flip it upside down, it's significantly faster. * Is the year divisible by 4? NO -> not leap year * YES -> Is the year divisible by 100? NO -> leap year * YES -> Is the year divisible by 400? NO -> not leap year * YES -> leap year This way you do only 1 division for 75% of years.
