# Booking rules & features

> Durations, opening hours, the daily budget, the booking horizon, privacy, and email notifications.

The same rules apply whether you book in the web app, the CLI, or through an agent. They are enforced on the server, so no client can work around them.

## The rules

| Rule             | What it means                                                                                                                                                                                            |
| ---------------- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| Time model       | Book any free time range, in 15-minute steps.                                                                                                                                                            |
| Minimum duration | 15 minutes.                                                                                                                                                                                              |
| Daily budget     | Up to **2 hours** of booking per person per Brussels calendar day.                                                                                                                                       |
| Booking horizon  | Up to **30 days** ahead, never in the past.                                                                                                                                                              |
| Opening hours    | Between **06:00 and 22:00** Europe/Brussels, within a single day. Applies when you create or edit a booking; bookings made before this rule existed stay valid, and admin maintenance blocks are exempt. |
| Edit             | Change your own booking until it starts.                                                                                                                                                                 |
| Cancel           | Cancel your own booking until it ends, so an in-progress booking you no longer need frees the room.                                                                                                      |
| Privacy          | Others see your **name** on a booking, never its **title**. Only you and admins see the title.                                                                                                           |

<Note>
  The daily budget counts only your **active** bookings. Cancel one and that time frees up again for the day.

You control confirmation emails, reminder emails, and how far ahead the reminder arrives on the **Notifications** tab of the **Account** page in the web app. The **API keys** tab on the same page manages the keys your CLI and agents use.

## Admins

WAT admins manage everything in the web app: they create, edit, and archive rooms, block rooms (these show as "Unavailable" on the calendar), view or cancel any booking, and manage members. Admin blocks take priority: if a block covers a time you had booked, your booking is cancelled automatically — it moves to your cancelled list and you receive an email asking you to reschedule. Blocks are exempt from the daily budget. Most members never need the admin area.
