# Leap
Welcome to Leap on Exercism's Haskell Track.
If you need help running the tests or submitting your code, check out `HELP.md`.
## Instructions
Given a year, report if it is a leap year.
The tricky thing here is that a leap year in the Gregorian calendar occurs:
```text
on every year that is evenly divisible by 4
except every year that is evenly divisible by 100
unless the year is also evenly divisible by 400
```
For example, 1997 is not a leap year, but 1996 is. 1900 is not a leap
year, but 2000 is.
## Notes
Though our exercise adopts some very simple rules, there is more to
learn!
For a delightful, four minute explanation of the whole leap year
phenomenon, go watch [this youtube video][video].

To complete this exercise you need to implement the function `isLeapYear`
that takes a year and determines whether it is a leap year.
