About the Star Dial Clock

Star Dial is a 24-hour clock in a starry sky. The same ring of today’s sky colours goes round once a day, with 00 at the top, fine ticks every 15 minutes and tonight shaded from sunset to sunrise, and a glowing bead with a comet trail travels it to now. In the corner, tonight’s moon shows its real phase.

The time is always in 24-hour figures, with the moon’s phase and the length of the night beneath it, and seconds can be shown too. Behind it the screen takes the colour of the real sky, from deep indigo before dawn to clear blue at noon and violet at dusk, worked out in your browser from today’s sunrise and sunset for your time zone. It asks for no location and sends nothing anywhere.
