The sun angles behind photography's best light — plus tonight's sunset, moon phase and shadow math, computed free.
Tonight's golden hour and blue hour, computed from sun elevation — the photographer's light windows with the angles that define them.
Exact rise, set, solar noon and day length for any place and date — the NOAA solar equations with the refraction fine print included.
Tonight's moon — phase name, illumination percent and age in days — for any date, with the next full and new moon.
Where exactly is the sun right now — elevation and compass azimuth for any time and place, for solar panels, shadows, photos and windows.
All three twilight boundaries for any date and place — when to stop flying VFR, when the horizon vanishes at sea, when the stars switch fully on.
Hours of daylight for any date and latitude, how fast it's changing, and the swing between your solstices.
How long a shadow anything casts at any time and place — height ÷ tan(sun elevation), with the direction it falls and the solar-design uses.
