About this tool

Behind this page sit the same NOAA solar equations photographers and sailors trust: Julian day, solar declination, the equation of time and the sunrise hour angle corrected for atmospheric refraction. Give it a latitude, longitude and date — type them, or press the geolocate button and approve the permission prompt — and it returns sunrise, solar noon, sunset, total day length and the golden-hour windows when light turns honey-colored and photos turn magical. Because every calculation runs locally in JavaScript, the tool works offline once loaded and never sends your location anywhere; the browser's geolocation API only fills the input fields, with a plain-English message if permission is declined. Polar edge cases are handled honestly: where the sun refuses to rise or set, the page says exactly that.
