Sunrise Sunset

Sunrise Sunset does exactly what its names says for iCal. It computes the times the sun rises and sets and produces an iCal calendar containing those events.

It is based on a little Basic program that did the sunrise and sunset calculation and has been gussied up with a better user interface and an iCal output back end. It is moderately accurate, so unless you are timing your sunrise or sunset experience to the minute, it can be quite useful.
