The Linnea calendar is a solar calendar with 13 months of 28 days each, for a total of 364 days. An extra day is added every four years to account for the leap year. The calendar was created by the Swedish botanist and physician Carl Linnaeus in the 18th century.
The Linnea calendar has several advantages over the Gregorian calendar. First, it is a perpetual calendar, meaning that it does not need to be adjusted for leap years. Second, it is more evenly distributed throughout the year, with each month having the same number of days. Third, it is based on the solar year, rather than the lunar year, which makes it more accurate.
