+
+            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.
