# Room Availability Finder

The Room Availability Finder is a scheduling tool: pick a start and end date/time, and it tells you which rooms are free and which are already booked for that window.

## Accessing the Room Availability Finder

From the administration panel, click **Rooms > Room availability finder**.

## What It Shows

After choosing a start and end date/time, every room on the current portal is checked against existing bookings and split into two lists:

* **Available rooms** — Free for the requested slot, shown with their title, branch, floor, and capacity
* **Occupied rooms** — Already booked, with the conflicting booking's title and time range

A room becomes "occupied" because it has been assigned to an attendance-tracking calendar entry, a course, or a specific session-course pairing for that time window — in other words, this checks real bookings made through the attendance and session tools, not a separate reservation calendar. This makes it a conflict-checker for physical rooms used in classroom or blended (in-person) session-based courses.

To assign a room to a course from the teacher side, see [Branches and Rooms](/3.x/teacher-guide/teacher-guide/branches-and-rooms.md) in the Teacher Guide.
