Dr. Regener Sun-Moon-Calendar calculates the sets, rises and phases of the sun and moon. It covers over 2000 locations in 110 countries. The program includes signs of the Zodiac, Saint's days, and days of Eclastical year, the moon in the Ecliptic, a graphical overview of the moons brightness, and time zone information and comparison. Other features include absolute local accuracy by management of own locations, pretty daily graphic, easy navigation and additional search functions, scientific calculation methods that involve even the influence of the moons distance, and the ability to print your own professional reports - monthly list, yearly overview etc. Aside from astronomers and astrologists, this program is very useful for people who need to know rises and sets like fishermen, hunters and other outdoor activists. Note that Rises and Sets may differ appreciably yet at distances of 100miles.
