+# Instructions
+
+Your task is to convert delivery date descriptions to _actual_ delivery dates, based on when the meeting started.
+
+There are two types of delivery date descriptions:
+
+1. Fixed: a predefined set of words.
+2. Variable: words that have a variable component, but follow a predefined set of patterns.
+
+## Fixed delivery date descriptions
+
+There are three fixed delivery date descriptions:
+
+- `"NOW"`
+- `"ASAP"` (As Soon As Possible)
+- `"EOW"` (End Of Week)
+
+The following table shows how to translate them:
+
+| Description | Meeting start                 | Delivery date                       |
+| ----------- | ----------------------------- | ----------------------------------- |
+| `"NOW"`     | -                             | Two hours after the meeting started |
+| `"ASAP"`    | Before 13:00                  | Today at 17:00                      |
+| `"ASAP"`    | After or at 13:00             | Tomorrow at 13:00                   |
+| `"EOW"`     | Monday, Tuesday, or Wednesday | Friday at 17:00                     |
+| `"EOW"`     | Thursday or Friday            | Sunday at 20:00                     |
+
+## Variable delivery date descriptions
+
+There are two variable delivery date description patterns:
+
+- `"<N>M"` (N-th month)
+- `"Q<N>"` (N-th quarter)
+
+| Description | Meeting start             | Delivery date                                             |
+| ----------- | ------------------------- | --------------------------------------------------------- |
+| `"<N>M"`    | Before N-th month         | At 8:00 on the _first_ workday of this year's N-th month  |
+| `"<N>M"`    | After or in N-th month    | At 8:00 on the _first_ workday of next year's N-th month  |
+| `"Q<N>"`    | Before or in N-th quarter | At 8:00 on the _last_ workday of this year's N-th quarter |
+| `"Q<N>"`    | After N-th quarter        | At 8:00 on the _last_ workday of next year's N-th quarter |
+
+~~~~exercism/note
+A workday is a Monday, Tuesday, Wednesday, Thursday, or Friday.
+
+A year has four quarters, each with three months:
+1. January/February/March
+2. April/May/June
+3. July/August/September
+4. October/November/December.

+# Introduction
+
+This week, it is your turn to take notes in the department's planning meeting.
+In this meeting, your boss will set delivery dates for all open work items.
+Annoyingly, instead of specifying the _actual_ delivery dates, your boss will only _describe them_ in an abbreviated format.
+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.
