# Leap
Given a year, report if it is a leap year.
The tricky thing here is that a leap year in the Gregorian calendar occurs:
```plain
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.
If your language provides a method in the standard library that does
this look-up, pretend it doesn't exist and implement it yourself.
## 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].

## Setup
Go through the setup instructions for JavaScript to
install the necessary dependencies:
http://exercism.io/languages/javascript
## Making the Test Suite Pass
Execute the tests with:
jasmine .spec.js
Replace `` with the name of the current exercise. E.g., to
test the Hello World exercise:
jasmine hello-world.spec.js
In many test suites all but the first test have been skipped.
Once you get a test passing, you can unskip the next one by
changing `xit` to `it`.
