Welcome to Leap on Exercism's PHP Track. If you need help running the tests or submitting your code, check out HELP.md.

Introduction

A leap year (in the Gregorian calendar) occurs:

• In every year that is evenly divisible by 4.
• Unless the year is evenly divisible by 100, in which case it's only a leap year if the year is also evenly divisible by 400.

Some examples:

• 1997 was not a leap year as it's not divisible by 4.
• 1900 was not a leap year as it's not divisible by 400.

• 2000 was a leap year!
