15 Minute Countdown Timer
A quarter of an hour: long enough to read a chapter, short enough to schedule.
How to Use the 15 minute Countdown Timer
Open the timer
This page is already set to 15:00. Press the start button and the countdown begins, with no setup and no signup.
Press F for fullscreen
The digits scale to fill the whole screen, so the remaining time stays readable from the back of a room, a classroom or a gym.
Keep the block visible
Use the subtitle to say what the 15 minute timer is for. A countdown with a name on it is much easier to come back to.
The bell ends it
An audible alert rings when the 15:00 countdown reaches zero, so you never have to watch the screen to know it is over.
Why Use This 15 minute Timer
A schedulable block
Fifteen minutes fits in most calendars and most classrooms, so the timer respects the rest of your day.
Readable at distance
In fullscreen the digits fill the screen, which is what you want when the display is across the room.
A real ending
The alert and the end state make the boundary of the block explicit, so you can close the task without drifting.
Nothing to install
It runs in the browser you already have open. No app, no account, no waiting for a download.
Where This Timer Helps
Fifteen minutes is one school period, one reading block and one decent chunk of focused work. It is a duration you can defend in a calendar because it fits inside a gap you already have.
This fifteen minute countdown gives you that block on screen. The digits scale to fill the display, the alert tells you when the time is up, and the link lets you hand the exact timer to somebody else.
Tips for making the most of it
- Use the subtitle to write the question you are going to answer in the next fifteen minutes.
- For a class or a workshop, project it and let the group see the remaining time.
- If you finish early, reset and use the extra minutes for a second pass.
