+ Special case of Sweden.
+
+ Sweden has a curious history. Sweden decided to make a gradual
+ change from the Julian to the Gregorian calendar. By dropping every
+ leap year from 1700 through 1740 the eleven superfluous days would
+ be omitted and from 1 Mar 1740 they would be in sync with the
+ Gregorian calendar. (But in the meantime they would be in sync with
+ nobody!)
+
+ So 1700 (which should have been a leap year in the Julian calendar)
+ was not a leap year in Sweden. However, by mistake 1704 and 1708
+ became leap years. This left Sweden out of synchronisation with
+ both the Julian and the Gregorian world, so they decided to go back
+ to the Julian calendar. In order to do this, they inserted an extra
+ day in 1712, making that year a double leap year! So in 1712,
+ February had 30 days in Sweden.
+
+ Later, in 1753, Sweden changed to the Gregorian calendar by
+ dropping 11 days like everyone else and this is what we use here.
