Sunrise Calculator
by Merlin
Sunrise Calculator computes and displays the times of sunrise and sunset, given a latitude, a longitude and a date.
The Widget can make allowances for altitudes of up to 15,240 metres (50,000 feet). The altitude compensation calculation, performed by the Widget, is not part of the published algorithm, on which the main calculation is based, and should be treated with caution.
This new version also computes and displays the times of moonrise and moonset.
