A rehearsal timer helps you see whether your talk fits its slot. Start by checking what the slot includes: just speaking, or also introductions, questions, and the handover? A fifteen-minute booking does not always mean fifteen uninterrupted minutes of presentation.
Budget the slot before opening the slides
For an example fifteen-minute slot, you might allocate two minutes to the opening, eight to the main explanation, two to the conclusion, and three to questions or handover. Adjust this to the actual brief. These segments are a planning example; the simple countdown does not automatically cue each one.
Write a short version of the conclusion before rehearsing. If you are behind, you then know what to retain. Removing a secondary example is usually easier than inventing an ending while watching the last seconds disappear.
Run an uninterrupted rehearsal
- Open the 15-minute timer or choose your actual duration.
- Test sound and decide whether it should be audible during the rehearsal.
- Start when you would begin speaking, not while still arranging windows.
- Keep the timer visible on the display you intend to use. Use Fullscreen when a dedicated timing screen is available.
- After zero, note the section where you were and which parts can be shortened.
For a first measurement without a fixed limit, use the stopwatch. For a second pass, use a countdown so you can see the remaining budget.
Separate the audience display from your notes
Check whether your computer is mirroring or extending its display. A fullscreen timer on a mirrored desktop may also be visible to the audience. If you use an extended display, verify which window is on the projector before the event begins.
This timer is a single-browser tool. It does not provide remote stage control, a synchronized director’s console, or automatic slide cues. Do not plan a live production around features it does not have.
Make the final minute a decision point
Choose a clear action for the final minute: deliver the conclusion, invite one final question, or hand over. Avoid treating zero as the moment to start deciding how to finish. For a meeting, write the next action and its owner before ending the slot.
Keep the device awake and prepare a backup time reference for an important event. If the page is hidden behind slides, read the background behavior guide. A visible clock or a human timekeeper can be a useful independent check.
