Digital Clock Online

Digital Clock Online is a distraction-free, full-screen digital clock that runs entirely in the browser. Six retro themes (three mechanical flip variants and three pixel LED variants) let you pick a look that matches your setup, from focus rooms to living-room streams. Time syncs to the device system clock for accuracy; the Wake Lock API keeps your screen on so it doubles as a real wall clock, bedside display, or presentation timer. 12/24-hour toggle, optional seconds and date, responsive across phones, tablets, and desktops. Free, no signup, no ads, and works offline after the first load.
