# 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:

```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].

## Resources

Remember to check out the Raku [documentation](https://docs.raku.org/) and
[resources](https://raku.org/resources/) pages for information, tips, and
examples if you get stuck.

## Running the tests

There is a test suite and module included with the exercise.
The test suite (a file with the extension `.rakutest`) will attempt to run routines
from the module (a file with the extension `.rakumod`).
Add/modify routines in the module so that the tests will pass! You can view the
test data by executing the command `raku --doc *.rakutest` (\* being the name of the
test suite), and run the test suite for the exercise by executing the command
`prove6 .` in the exercise directory.
