How It Works
This calculator uses the SunCalc library, which implements astronomical algorithms for solar position calculations. It computes the sun's position as a function of latitude, longitude, and date, then derives the exact moments when the sun crosses key angular thresholds (horizon, -6°, -12°, -18°).
Solar Angles
Sunrise/Sunset: sun at 0° altitude
Civil twilight: −6° altitude
Nautical twilight: −12°
Astronomical twilight: −18°
