From Sweden probably and told wrong.  It was the intention that starting
1700 they would omit leap years until they were in sync with the Gregorian
calendar.  So 1700 was not a leap year.  But they forgot about that or
something and they made 1704 and 1708 leap years, so they did not gain
on the Gregorian calendar and were one day out of sync with the Julian
calendar.  In 1712 they got back in sync with Julian by adding a
February 30.  They finally changed later that century (1768 if I remember
right).

But what this is doing in all those newsgroups...
