*** 172,178 **** All internal computations assume the Gregorian calendar system. When you use the "julian" modifier, it does not convert the date into a real Julian calendar date, it merely shifts the Gregorian calendar date to - align it with the Julian calendar. This means that the "julian" modifier will not work right for dates that exist in the Julian calendar but which do not exist in the Gregorian calendar. --- 172,177 ----
