Analogue Clock

About this tool

Reads the time directly from your device's own clock and timezone, so it's always correct without needing to set anything. The second hand sweeps smoothly rather than ticking once a second, using your browser's animation frame timing. Press Fullscreen to fill the screen — handy on a second monitor, a tablet propped up on a desk, or projected in a room.

Does it use my computer's clock or an internet time server?

Your device's own system clock. If that clock is wrong, the display will be too — check your device's date and time settings if it looks off.

Does fullscreen keep my screen awake?

That depends on your device and browser's own power settings, not on this tool; some devices will still dim or lock after their normal idle timeout.
