Sol Clock

Know when the sun and moon rise, set, and every phase of light. Your sky, your clock, your light. “Let each builder choose with care how to build” (1 Cor 3:10)

Sol Clock is a solar time clock connecting you to the rhythm of the sun and moon. Sol Clock shows you where the sun actually is, from nautical dawn through solar noon to deep night. Displayed on a beautifully crafted astronomical clock face inspired by the medieval clocks of Venice and Prague. Sol Clock displays true solar time alongside standard and UTC, so you always know where you stand in the actual solar day, not just the civil one.

The Clock The clock face renders a full 24-hour solar day. The hand tracks the sun's position through the light spectrum of the day. The orbital ring shows the complete sky color spectrum for the day. Computed dynamically based on your location and the day's sunrise and sunset times.

Sky Map The Sky Map shows an equidistant northern projection center on the North Pole with a live terminator line showing the boundary between day and night.

Solar Compass The Solar Compass tracks the sun and moon in real time and shows their current relationship to the Equator and Tropics of Cancer and Capricorn.
