A few years later they changed their minds and reverted back to the Julian Calendar by having two leap days in 1712, the 29th and 30th of February. http://www.naturalistsalmanac.com/0230.html In the Soviet Revolutionary Calendar, all months had 30 working days, and the year was padded out with 5 or 6 "monthless" holidays. The Soviet Revolutionary Calendar doesn't appear to have actually been used. In the French Republican Calendar, all months had 30 days and the year was padded out with 5 or 6 "monthless" holidays, called sansculottides . However, the French Republican months don't correspond with the months of the Gregorian calendar, since its year starts at the autumnal equinox (September 23 plus or minus 1 day). -- Mike Williams Gentleman of Leisure
