The day
Day length
Day length is the time from sunrise to sunset, and it changes with the season and your latitude.
It changes fastest at the equinoxes and stands still at the solstices; at the equator it barely moves all year.
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.
Day length, 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 this minute. Slide through the day, or drag the sky to turn it.
How Sol measures it.
From sunrise to sunset, the upper edge at a sea horizon. At the equator it holds near twelve hours all year; at 60° north it runs from under six hours in December to over eighteen in June; inside the polar circles it reaches zero and twenty-four. Refraction adds a few minutes at both ends.
Make time for the light.
