What this calculator will compute
Inputs: latitude (deg), longitude (deg) and date range (date range).
Outputs: day length (h:mm), change per day (min) and annual maximum and minimum (h:mm).
Formula, recorded as scope and not yet verified against a primary source: Day length is the interval between sunrise and sunset from the same NOAA hour-angle solution; the daily change is the derivative of that interval, which peaks near the equinoxes and approaches zero at the solstices.
