the month February has in the Julian and Gregorian calendar only 28, in leap years 29 days. There were however three historical events, at those 30. February existed.

1700 decided Sweden, ofto change Julian to the Gregorian calendar. The idea was to do without for the next 40 years simply on the leap years in order to adjust the daily difference between Julian and Gregorian calendar. Thus became in the year 1700 of the 29. February jumped over. In the following leap years 1704 and 1708there were by mistake nevertheless the 29. February. The decision was cancelled finally again and again the Julian calendar was used. Since Sweden now the time calculation of this calendar one day ahead was, additional day had to be added: this was the 30. February 1712. The regulation applied also to Finland then dependent on Sweden. 1753 changed Sweden then finally to the Gregorian calendar.

1929 had wanted to introduce the Soviet Union a revolutionary calendar, in which each month should have 30 days. The remaining days of a yearly were then„monthlyless holidays so mentioned “. Thus there were 30 in the Soviet Union 1930 and 1931. February. But 1932 were again rejected this calendar.

Probably a legend is the statement that in the Julian calendar of the years 44 v. Chr. to 8 v. Chr.February normally29 days and in leap years was 30 days long. This is to have then been changed by emperor Augustus, so that the month designated after him would get August the same length as July designated after Julius Caesar. There are however no historical sources for thoseStatement.

A legend is probably likewise the statement that in the calendar of the years 541 n. Chr. to 572 n. Chr. due to a false reading of the Romana supputatio vetus in some monasteries of central France February regularly around one day too long was, because the balance day for thatOsterzyklus (the so-called Saltus lunae) was used inadvertently in this month. There are however no historical sources for the statement.

Besides there are different calendar drafts, in which February has 30 or more days.
