Sunrise Sunset Calculator

A sunrise sunset calculator computes the exact time the sun crosses the horizon at a given location and date — plus the surrounding twilight boundaries (civil, nautical, astronomical) and photographer-favored windows (golden hour, blue hour). Photographers, landscape designers, boaters, hikers, observers, and anyone planning an outdoor shot benefit from knowing these times to the minute. The math relies on the sun's position relative to the observer, which depends on latitude, longitude, and the time of year — not on weather or atmosphere alone. This calculator uses the SunCalc library, which implements NOAA's solar-position algorithm and is accurate to within a minute at most latitudes. Pick from 150+ pre-loaded major cities, use your browser's geolocation, or enter coordinates manually. Pair it with the Time Zone Converterif you're coordinating shoots across multiple zones, or the Days Until Calculator to count down to a specific event date.
