# Instructions
2+
3+
Your task is to convert delivery date descriptions to _actual_ delivery dates, based on when the meeting started.
4+
5+
There are two types of delivery date descriptions:
6+
7+
1. Fixed: a predefined set of words.
8+
2. Variable: words that have a variable component, but follow a predefined set of patterns.
9+
10+
## Fixed delivery date descriptions
11+
12+
There are three fixed delivery date descriptions:
13+
14+
- `"NOW"`
15+
- `"ASAP"` (As Soon As Possible)
16+
- `"EOW"` (End Of Week)
17+
18+
The following table shows how to translate them:
19+
20+
| Description | Meeting start | Delivery date |
21+
| ----------- | ----------------------------- | ----------------------------------- |
22+
| `"NOW"` | - | Two hours after the meeting started |
23+
| `"ASAP"` | Before 13:00 | Today at 17:00 |
24+
| `"ASAP"` | After or at 13:00 | Tomorrow at 13:00 |
25+
| `"EOW"` | Monday, Tuesday, or Wednesday | Friday at 17:00 |
26+
| `"EOW"` | Thursday or Friday | Sunday at 20:00 |
27+
28+
## Variable delivery date descriptions
29+
30+
There are two variable delivery date description patterns:
31+
32+
- `"<N>M"` (N-th month)
33+
- `"Q<N>"` (N-th quarter)
34+
35+
| Description | Meeting start | Delivery date |
36+
| ----------- | ------------------------- | --------------------------------------------------------- |
37+
| `"<N>M"` | Before N-th month | At 8:00 on the _first_ workday of this year's N-th month |
38+
| `"<N>M"` | After or in N-th month | At 8:00 on the _first_ workday of next year's N-th month |
39+
| `"Q<N>"` | Before or in N-th quarter | At 8:00 on the _last_ workday of this year's N-th quarter |
40+
| `"Q<N>"` | After N-th quarter | At 8:00 on the _last_ workday of next year's N-th quarter |
41+
42+
~~~~exercism/note
43+
A workday is a Monday, Tuesday, Wednesday, Thursday, or Friday.
44+
45+
A year has four quarters, each with three months:
46+
1. January/February/March
47+
2. April/May/June
48+
3. July/August/September
49+
4. October/November/December.

# Introduction
2+
3+
This week, it is your turn to take notes in the department's planning meeting.
4+
In this meeting, your boss will set delivery dates for all open work items.
5+
Annoyingly, instead of specifying the _actual_ delivery dates, your boss will only _describe them_ in an abbreviated format.
6+
As many of your colleagues won't be familiar with this corporate lingo, you'll need to convert these delivery date descriptions to actual delivery dates.
