// Calculating a Leap Year

// Divide the year you want to check by 4. If it is not evenly divisible (it has a remainder), it's is not a leap year. If it is evenly divisible (it has no remainder) continue to step 2.
// Divide the year by 100. If the year is evenly divisible by 4 but is not evenly divisible by 100, it is a leap year. If it is evenly divisible by both 4 and 100, continue to step 3.
// Divide the year by 400. If the year is evenly divisible by 100, but is not evenly divisible by 400, it is not a leap year. If it is evenly divisible by both 100 and 400, it is a leap year.
