Sun Clock is a 24‑hour clock that displays the position of the sun, times of sunrise, solar noon, sunset, golden hour, and twilight for your current location. It also shows the position and phase of the moon, and its rising and setting times.

In the Northern Hemisphere the sun moves across the sky in a clockwise direction, while in the Southern Hemisphere it moves anti‑clockwise. Sun Clock matches this by setting its direction of rotation based on your latitude; you can change it in the settings. Additional options include a ticking seconds hand, showing odd numbers on the clock face, and using 12‑hour times.

Updates: Added an MIT license on 2026-06-26, a ticking seconds hand on 2026-03-12, a Safari bug fix on 2026-01-01, odd‑number display and 12‑hour face changes on 2024-05-23, an annual calendar on 2024-02-13, PWA support on 2023-10-20, auto‑color mode on 2022-10-24, dark mode on 2022-09-07, and live updates for all times.

Sun Clock is free, ad‑free, and collects only aggregate stats. Your location and settings are stored locally in the web browser. Tap or hover over segments, the moon, the hour hand, or the centre dot to see start and end times. Feedback is welcomed.
