This program also handles negative JD Numbers. Entering a blank JD Number argument defaults to the current date JD Number (UT). A starting calendar date can also be used, such as: 'BC 1949-5-20' or '2025-Feb-24' or 'AD 170-Nov-03' The number of days represents the number of days leading up to or following the starting point. If the number of days is positive, the listing will begin on the starting JD number and span that many days after. If the number of days is negative, the listing will begin that many days prior to and span from there up to the starting point. If a calendar column has dots ...... in it, it means that the given JD number is outside the valid range on that calendar. It may sometimes be a valid JD number on one calendar but not on the other. As a general rule, this only happens near the ends of the calendar system, which should not really pose any serious problem for general use.
