Ready
30:00Add or take time off while it runs with the buttons under the clock. The countdown is worked out from the clock, so a tab left in the background comes back correct.

Thirty minutes covers a standard meeting slot, a typical workout-class length, a sitcom episode, or a solid single block of focused work or study. It is long enough that most people check on it only once or twice rather than watching the whole way through.
The countdown loads pre-set to thirty minutes here, full screen and legible from across a room, with a chime at zero or a silent flashing screen if sound would be unwelcome. It stays exact even after a long stretch in a background tab.
Need a different length? The full timer page has quick presets from ten seconds to ten minutes plus a custom field for anything else, and pairs well with charades cards, bingo cards and word searches if you are running a game rather than a work session.
FAQ
Is this timer free?
Yes, completely, no signup, no account and no limit on how many times you run it. Pick it and press start.
What is a 30 minute timer commonly used for?
A standard meeting slot, a workout class, a single block of study or focused work, or timing a TV-length break, it is one of the most generally useful lengths for planning a chunk of a day.
Does it keep correct time in a background tab?
Yes. The countdown is worked out from the clock rather than counted tick by tick, so a tab you switched away from comes back showing the correct time even if the browser paused it while it was hidden.
