Clock with Seconds
A free online clock with seconds that shows minutes and seconds in large, clear digits. Set a time and it counts down to zero and sounds an alarm, or leave it running as a visible minutes-and-seconds display. There is nothing to install and no account to create, and it works full screen on any phone, tablet, or computer.

How to use it
- Type your minutes and seconds into the display, or use the quick preset chips.
- Press Start, or the spacebar, to begin. Pause and Reset control the run at any time.
- Switch to full screen for a large minutes-and-seconds display that reads across a room.
- An alarm plays when it reaches zero, so you do not have to watch the screen.
Common use cases
- A large, visible seconds display for a classroom, office, or studio

- Any task where you want minutes and seconds shown at a glance
