# Meetup
2+
3+
Calculate the date of meetups.
4+
5+
Typically meetups happen on the same day of the week. In this exercise, you
6+
will take a description of a meetup date, and return the actual meetup date.
7+
8+
Examples of general descriptions are:
9+
10+
- The first Monday of January 2017
11+
- The third Tuesday of January 2017
12+
- The wednesteenth of January 2017
13+
- The last Thursday of January 2017
14+
15+
The descriptors you are expected to parse are:
16+
first, second, third, fourth, fifth, last, monteenth, tuesteenth, wednesteenth,
17+
thursteenth, friteenth, saturteenth, sunteenth
18+
19+
Note that "monteenth", "tuesteenth", etc are all made up words. There was a
20+
meetup whose members realized that there are exactly 7 numbered days in a month
21+
that end in '-teenth'. Therefore, one is guaranteed that each day of the week
22+
(Monday, Tuesday, ...) will have exactly one date that is named with '-teenth'
23+
in every month.
24+
25+
Given examples of a meetup dates, each containing a month, day, year, and
26+
descriptor calculate the date of the actual meetup. For example, if given
27+
"The first Monday of January 2017", the correct meetup date is 2017年1月2日.
28+
29+
## Setup
30+
31+
Go through the setup instructions for Javascript to install the necessary
32+
dependencies:
33+
34+
[https://exercism.io/tracks/javascript/installation](https://exercism.io/tracks/javascript/installation)
35+
36+
## Requirements
37+
38+
Install assignment dependencies:
39+
40+
```bash
41+
$ npm install
42+
```
43+
44+
## Making the test suite pass
45+
46+
Execute the tests with:
47+
48+
```bash
49+
$ npm test
50+
```
51+
52+
In the test suites all tests but the first have been skipped.
53+
54+
Once you get a test passing, you can enable the next one by changing `xtest` to
55+
`test`.
56+

Jeremy Hinegardner mentioned a Boulder meetup that happens on the Wednesteenth of every month [https://twitter.com/copiousfreetime](https://twitter.com/copiousfreetime)

61+
## Submitting Incomplete Solutions
62+
63+
It's possible to submit an incomplete solution so you can see how others have
64+
completed the exercise.
