This calculator uses a simplified solar-position approximation: it estimates the sun’s declination angle for the day of year, combines it with your latitude to find the hour angle at sunrise/sunset, and converts that into total daylight hours. It’s a widely used approximation for daylight length, though exact sunrise/sunset times also depend on longitude and time zone, which aren’t factored in here.
