message:
* calc/calc.el (calc-gregorian-switch): New variable.
* calc/calc-forms.el (math-day-in-year, math-dt-before-p)
(math-absolute-from-gregorian-dt, math-absolute-from-julian-dt)
(math-date-to-julian-dt, math-date-to-gregorian-dt): New functions.
(math-leap-year-p): Add option to distinguish between Julian
and Gregorian calendars.
(math-day-number): Use `math-day-in-year' to do the computations.
(math-absolute-from-dt): Rename from `math-absolute-from-date'.
Use `math-absolute-from-gregorian' and `math-absolute-from-julian'
to do the computations.
(math-date-to-dt): Use `math-date-to-julian-dt' and
`math-date-to-gregorian-dt'
to do the computations.
(calcFunc-weekday, math-format-date-part): Use the new version of the DATE to
determine the weekday.
(calcFunc-newmonth, calcFunc-newyear): Use `calc-gregorian-switch' when
necessary.

+Otherwise, it should be a list `(YEAR MONTH DAY)' when Calc begins to use
+the Gregorian calendar; Calc will use the Julian calendar for earlier dates.
+The dates in which different regions of the world began to use the
+Gregorian calendar vary quite a bit, even within a single country.
+If you want Calc's date forms to switch between the Julian and
+Gregorian calendar, you can specify the date or choose from several
+common choices. Some of these choices should be taken with a grain
+of salt; for example different parts of France changed calendars at
+different times, and Sweden's change to the Gregorian calendar was
+complicated. Also, the boundaries of the countries were different at
+the times of the calendar changes than they are now.
+The Vatican decided that the Gregorian calendar should take effect
+on 15 October 1582 (Gregorian), and many Catholic countries made
+the change then. Great Britian and its colonies had the Gregorian
+calendar take effect on 14 September 1752 (Gregorian); this includes
+the United States."
