28 hours
The online timer for 28 hours keeps an accurate count down and immediately shows how many 28 hours are in minutes. The interface is minimal: start, pause, and reset are located under the counter. Full-screen mode speeds up focus, and you can adjust or disable the end sound.
The timer works on all devices and doesn't crash when switching tabs. The remaining time is duplicated in the browser header.
