+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

+calendar take effect on 14 September 1752 (Gregorian); this includes
