30th feb in which year

In order to fully sync the calendar with the lunar year, the Roman king Numa Pompilius added January and February to the original 10 months. February is the only month to have a length of fewer than 30 days. Originally, February was made the last month of the calendar year. The month after that was Xanthicus or April.

Unfortunately, the plan went awry. For some reason, the Empire forgot to skip the leap years in both and — they had managed to drop only one day in eight years, and, even worse, were now no longer aligned with other holdouts still using the Julian calendar.

So the King decided to fix the problem in Instead of simply dropping ten more days and joining the Gregorian nations, he instead rejoined the Julian ones. In , the Empire had two leap days — one as usual, and one to make up for the lost day in This is confirmed by successive dates found in daily issues of Pravda , the official newspaper of the Communist Party, in which February had 28 days in and , in accordance with the Gregorian calendar.

The Soviet revolutionary calendar was discarded as it was difficult to eliminate the Sunday rest tradition. The original seven-day week was restored in The 13th century scholar Johannes de Sacrobosco claimed that February had 30 days in leap years between 45 BCE and 8 BCE in the Julian calendar, when February was shortened to give the month of August the same length as the month of July.
