1 Hour Timer

1 Hour Timer — Free, Shareable, In Sync

One hour covers a full class, a standard exam block, or a meeting you'd like to actually end on time. Start the countdown and share the link so nobody has to ask how long is left.

Common questions

Is an hour timer displayed differently from a shorter one?

Yes — once a countdown includes hours, the board shows HH:MM:SS instead of just MM:SS, and that format is fixed for the whole hour so the display never jumps or changes shape partway through.

Can I use this for a one-hour meeting to help it end on time?

Yes — share the link at the start and leave it visible on a shared screen or everyone's own device; watching the same clock count down is a simple, effective way to keep a meeting on schedule.

What happens after the hour runs out?

The board reads zero and every screen with the link chimes together (if sound is on) — it doesn't restart or do anything else automatically.
