Local clock time (HST). Sunrise and sunset when the sun's center is 0.833° below the horizon; civil twilight at 6°.

How these times are computed

Each row runs the SunCalc solar model for the stored capitol coordinate, 21.307° N, 157.858° W, and converts the result to local clock time with the Pacific/Honolulu time zone rules. Times assume a flat, open horizon at sea level. Hills, buildings and elevation shift what you see by a few minutes. The sunrise and sunset guide walks through the calculation.
