# 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 lists how to translate them:
19+
20+
| Description | Meeting start | Delivery date |
21+
| ----------- | ---------------------------- | ----------------------------------- |
22+
| `"NOW"` | - | Two hours after the meeting started |
23+
| `"ASAP"` | Before 12:00 | Today at 17:00 |
24+
| `"ASAP"` | After 12:00 | Tomorrow at 12:00 |
25+
| `"EOW"` | Monday, Tuesday or Wednesday | Friday at 5:00 |
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 | Delivery date |
36+
| ----------- | ---------------------------------------------------------------------- |
37+
| `"<N>M"` | At 8:00 on the _first_ work day<sup>1</sup> of this year's N-th month |
38+
| `"Q<N>"` | At 8:00 on the _last_ work day<sup>1</sup> of this year's N-th quarter |
39+
40+
<sup>1</sup> A work day is either a Monday, Tuesday, Wednesday, Thursday or Friday.

# Introduction
2+
3+
This week, it is your turn to take notes in your 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 date, your boss will only _describe them_.
6+
It is your task to convert these (short) descriptions to actual delivery dates.
