In Sweden and (what is now) Finland, they started to use a weird system
for slowly changing from Julian to Gregorian calendar systems. 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.

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).
