The day

Solar noon

Solar noon is the moment the sun is highest in your sky, and it is rarely at twelve on the clock.

Time zones and the equation of time push it as much as an hour either way; shadows are shortest then.

Shadow length now

Golden hour, the twilights and the moon, where you stand.

Sol for iPhone is coming soon, with each of them for the place you stand, on your phone and your wrist.

Solar noon, where you stand.

You stand at the middle of your horizon. The dots are the sun’s path today, warm where the light turns golden; the stage opens at solar noon. Slide through the day, or drag the sky to turn it.

How Sol measures it.

The clock says twelve at solar noon only at the centre of a time zone on four days a year. The rest of the time your longitude within the zone shifts it by four minutes per degree, and the Earth's tilted, elliptical orbit adds the equation of time — up to sixteen minutes either way — on top.

Make time for the light.
