How these times are computed

Each row runs the SunCalc solar model for the stored capitol coordinate, 30.274° N, 97.740° W, and converts the result to local clock time with the America/Chicago 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.
