-#
-# In 1700, Denmark made the transition from Julian to Gregorian.  Sweden
-# decided to *start* a transition in 1700 as well, but rather than have one of
-# those unsightly calendar gaps :-), they simply decreed that the next leap

-# different from both Julian and Gregorian for a period of 40 years.
-#
-# However, in 1704 something went wrong and the plan was not carried through;
-# they did, after all, have a leap year that year.  And one in 1708.  In 1712
-# they gave it up and went back to Julian, putting 30 days in February that
-# year!...
-#
-# Then in 1753, Sweden made the transition to Gregorian in the usual manner,
-# getting there only 13 years behind the original schedule.
-#
-# (A previous posting of this story was challenged, and Swedish readers
-# produced the following references to support it: "Tiderakning och historia"
-# by Natanael Beckman (1924) and "Tid, en bok om tiderakning och
