# Leap
Write a program that will take a year and 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].

### Submitting Exercises
Note that, when trying to submit an exercise, make sure you're exercise file you're submitting is in the `exercism/csharp/<exerciseName>` directory.
For example, if you're submitting `bob.cs` for the Bob exercise, the submit command would be something like `exercism submit <path_to_exercism_dir>/csharp/bob/bob.cs`.
