Their method? To skip the next 11 leap year days on years divisible by four (no leap year days through 1740). On Feb 29, 1700, Julian-1 calendar it was Mar 1, 1700 Julian-Sweden-1 calendar. On that day, it was one day ahead of the Julian-1 calendar, and 10, instead of 11, days behind the Gregorian calendar. To further confuse matters, also in use is the Julian-3-25- calendar, which matches the Julian-1's dates, but its yearly Number Change Day wasn't on January 1st, but on March 25th.
The plan for Sweden was to shorten the day gap between the calendar they were using and the Gregorian calendar they wanted to use in 1741. by coming one day closer every fourth March 1st in years divisible by four until the use of a leap year resumes with the calendar of 1741.
This change further added confusion between countries on what day it was for commerce and trade. As you can see from the chart below between the four calendars in use by various European countries, it was calendar anarchy in the U.K., Europe, the Meditteranean and elsewhere!

Who knew which countries were using what calendars? Total confusion. You have the Julian-Sweden calendar being used in only one country. It was clearly obvious it wasn't going to work.
Furthermore, the Great Northern War made the people in charge of the Julian-Sweden calendar forget to skip omitting the Feb 29, 1704 and Feb 29, 1708 leap year days, making the calendar stuck one day ahead of the Julian-1 calendar.
In January 1711, King Charles XII issued a command that Sweden would retreat from using the altered calendar, and return to using the Julian-1 calendar on March 1, 1712. To achieve lining up the dates with the two calendars, a second extra day was added to February of 1712, the day after the 29th modestly called February 30, 1712. This made the calendar 367 days long just for that year. As you can see at the top of the above chart, this is how the dates lined up after February 30, 1712, Julian-Sweden calendar date.
In the year 1753, a year after England and its colonies, Sweden adopted the Gregorian calendar. February 17 being followed by March 1, the transition was complete.
