Know your light before you shoot.

Sunrise, sunset, golden hour, blue hour — computed for your city and date from NOAA’s public-domain solar formulas, spot-validated against official almanacs, and explained in plain language. Built for photographers, filmmakers and anyone whose work depends on the angle of the sun.

Why trust these numbers?

Because we show them. Our engine implements the NOAA Global Monitoring Laboratory solar-position formulas (public domain) and was spot-validated against the official Hong Kong Observatory Almanac 2026 and Taiwan CWA 2026 Taipei table: 43 published values checked, 36 matched to the minute, worst deviation 3 minutes.
