Reading the sky band

The band is one day in Lahti, midnight to midnight, in its own local time. The curve is the sun's height: above the line it is up, below it is not. The dark bands are the three twilights and night; the lighter stripe either side of sunrise and sunset is the golden hour, and the thin cool stripe after it is the blue hour. Drag the sun to any minute and the readout says how high it is and which way to look.

Dawn, sunrise, dusk and the three twilights

Sunrise and sunset are when the top edge of the sun meets a flat horizon, with refraction bending the light so it shows up a little early and lingers a little late (the sun's centre is 0.833 degrees below the horizon at that moment). Civil twilight is the sun within 6 degrees below: bright enough to work outside without lights. Nautical twilight runs to 12 degrees, when sailors could still see the horizon to shoot a star. Astronomical twilight runs to 18 degrees; after that the sky is as dark as it gets.

Why the times drift

Day length in Lahti changes fastest around the equinoxes in March and September and stalls at the solstices in June and December. The change column in the table is today against yesterday, so you can watch the evenings draw in or stretch out. Hills, buildings and haze at your actual horizon shift the real moment by a minute or several; these are the times for a flat, clear horizon at sea level.

What stays here

Everything on this page is arithmetic on a latitude, a longitude and the clock, done once at the edge so the numbers are in the page before any script runs, and again in your browser as you drag the sun. No account, no cookies, nothing typed here is stored. The only thing this page records is that a city was looked up, and which one.
