# Timekeeper: the speaker's clock on a stage screen

> Timekeeper runs a countdown for each talk on a screen facing the stage, turns yellow and red as time runs out, and sends the speaker prompts like Please wrap up.

Timekeeper is for talks, panels and classes. It shows the speaker a large clock on a screen facing the stage, counts down the time of each talk, and lets you send short prompts from the console without walking on stage.

## Before you start

Timekeeper needs a screen that faces the stage. Pair a screen in [Big screen](https://docs.luce.show/modes/big-screen.md), open its settings and set it to face the stage.

## Sessions and talks

A session is a part of the programme with talks in it, such as one slot of the agenda. You can have up to 20 sessions, each with up to 30 talks.

**1. Add a session**

Choose **New session**, give it a name and, if you like, link it to an agenda slot. The agenda keeps the slot as it is; the session times the talks inside it.

**2. Add its talks**

For each talk, set a **Title**, an optional **Speaker** and a **Length** between 1 and 240 minutes.

**3. Set the warnings**

**Yellow at** and **Red at** set how many seconds before the end the speaker's clock changes colour. Past zero it counts on in red.

## On stage

The **On stage** panel runs the talk on the stage screen:

* **Start**, **Pause** and **Next talk**.
* **−1** and **+1** take a minute away or add one; the reset button goes back to the talk's full time.
* **Flash**, **Blackout** and **Clear stage** for the moments in between.

The panel also shows whether the session is on time, behind or ahead of plan.

## Prompts

A prompt is a short line under the speaker's clock, such as **Please wrap up**, **Time for questions**, **Speak up**, **Slow down** or **Stop now**. You can write your own and keep up to 12. **Urgent** prompts show in red. The next talk takes a prompt down, or choose **Take down**.
