Three minutes is the classic egg timer interval, and it remains the reference point for a soft-boiled egg, for most black tea steeping, and for the standard round in amateur boxing. It is also the length used for lightning talks and elevator pitches at conferences, and the interval many instrumental practice routines use for a single focused repetition. The page opens with 180 seconds already set. The countdown works from a fixed end time rather than counting ticks, so background tab throttling does not make it drift, and it alerts you at zero. This matters for cooking in particular, where being thirty seconds late genuinely changes the result. If you need something either side of this, 2 Minute Timer and 5 Minute Timer behave identically with different starting values.
Countdown Timer is a flexible tool that covers both short-duration timers measured in minutes and seconds and long-duration countdowns to calendar dates measured in days, hours, minutes, and seconds. Short-duration timers are the more common daily use case: a 20-minute timer for a Pomodoro work session, a 7-minute timer for a rest between sets, a 12-minute timer for cooking pasta. Long-duration countdowns are used for event planning and motivation: a website launch date, a product release, an exam or presentation deadline, or a personal milestone. The audio alert at zero ensures the timer is useful even when the browser tab is not visible, such as when cooking or exercising and the screen is not being watched. For structured interval-based work, Pomodoro Timer provides an automated version that cycles through work and break periods without requiring manual resets, which is more convenient than manually setting a countdown timer for each session. Countdown Timer is more flexible for one-off or non-standard durations. The timer uses the browser's requestAnimationFrame loop for the display update and tracks elapsed time using the high-resolution performance.now() API, which provides accuracy that is not affected by the system clock being adjusted during the countdown. The tool works reliably when the browser tab is in the background on desktop browsers, though mobile browsers may throttle background JavaScript execution to reduce battery drain. The tool runs free in the browser without installation.
