3 Minute Timer

Press start and this 3 minute timer counts down 180 seconds to zero — full screen if you want it, with a gentle chime or a silent green flash when time is up. The 3 minute timer is one of the most-used timers on the web: roughly 165,000 US searches a month (Semrush, 2026). This page is free, with no ads and no sign-up, works offline once loaded, remembers your volume on this device, and shows the exact clock time it will finish — so one glance tells you where you stand. It is built for microwave waits, short breathing exercises, and board-game turns.

Frequently asked questions

What breathing exercise fits in 3 minutes?

Three minutes holds about 10 cycles of box breathing (4 seconds in, 4 held, 4 out, 4 held) or roughly 12 slow physiological sighs, both formats studied for lowering acute stress. Use the disc view and watch the wedge shrink while you breathe; the silent flash tells you when you are done without a sound.

How do I make the 3 minute full screen?

Press Start, then click the Fullscreen button (or press F). The whole window becomes nothing but the timer: digits big enough to read from across a classroom or office. Press Esc to leave full screen; the timer keeps running either way.

Does the 3 minute make a sound when time is up?

Only if you want it to. The default chime is a soft, synthesized two-note tone, not a harsh buzzer. Drag the volume slider to set the level, or mute it entirely: when muted, the screen flashes fern green instead, so a silent room stays silent. Your setting is remembered on this device.

Can I use the 3 minute offline?

Yes. The page is a single self-contained file with no external requests beyond Cloudflare’s privacy-respecting, cookie-less page-view counting, and it installs as a PWA: after your first visit, the timer keeps working with no network at all. That makes it reliable on school networks, planes, and dead zones.

How many seconds is 3 minutes?

3 minutes is exactly 180 seconds. If you need a different length, the All timers page links every preset from 1 to 90 minutes and 1 hour, and each page switches between a shrinking-disc view and plain digits.
