How does CyberSky handle Julian and Gregorian calendar dates?
CyberSky uses the Julian calendar for all dates up to October 4, 1582, and the Gregorian calendar for all dates from October 15, 1582 onward. If you enter one of the ten dates that were eliminated by the introduction of the Gregorian calendar, it will be converted to a Gregorian calendar date for you. For example, if you enter October 5, 1582, the program will convert that date to October 15, 1582.
