# Leap
|
||
|
|
|
||
|
|
Welcome to Leap on Exercism's Elixir 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].
