Today is the first day of the month of Vendémiaire of the year 234 -- if you are following the calendar of the First French Republic.
The revolutionaries were really revolutionary in those days -- they wanted to get the regime and the church out of the passage of time as well as everything else, so they instituted a calendar that started on this day (22 September) in 1792; it has 12 months with 3 weeks in each month. Each month has 10 days and each day has 10 hours and each hour has 100 minutes and each minute has 100 seconds.
The months were named after poetic descriptions of the time of year.

It seemed like a good idea at the time, but it didn't catch on, and was hard to coordinate with those old fuddy duddys in neighboring lands. They switched back to the Gregorian version of the calendar at the end of 1805.
At least they tried, non?
