# Meetup

Calculate the date of meetups.

Typically meetups happen on the same day of the week.  In this exercise, you will take
a description of a meetup date, and return the actual meetup date.

Examples of general descriptions are:

- the first Monday of January 2017
- the third Tuesday of January 2017
- the Wednesteenth of January 2017
- the last Thursday of January 2017

Note that "Monteenth", "Tuesteenth", etc are all made up words. There
was a meetup whose members realized that there are exactly 7 numbered days in a month that
end in '-teenth'. Therefore, one is guaranteed that each day of the week
(Monday, Tuesday, ...) will have exactly one date that is named with '-teenth'
in every month.

Given examples of a meetup dates, each containing a month, day, year, and descriptor 
(first, second, teenth, etc), calculate the date of the actual meetup.
For example, if given "First Monday of January 2017", the correct meetup date is 2017/1/2
 

## Hints

To complete this exercise, you need to implement the `meetupDay` function.

You will find the type signature for `meetupDay` already in place,
but it is up to you to define the function.



## Getting Started

For installation and learning resources, refer to the
[exercism help page](http://exercism.io/languages/haskell).

## Running the tests

To run the test suite, execute the following command:

```bash
stack test
```

#### If you get an error message like this...

```
No .cabal file found in directory
```

You are probably running an old stack version and need
to upgrade it.

#### Otherwise, if you get an error message like this...

```
No compiler found, expected minor version match with...
Try running "stack setup" to install the correct GHC...
```

Just do as it says and it will download and install
the correct compiler version:

```bash
stack setup
```

## Running *GHCi*

If you want to play with your solution in GHCi, just run the command:

```bash
stack ghci
```
