-:--.--

Decimal time divides the day into 10 hours, each hour into 100 minutes, and each minute into 100 seconds. The time shown counts from local midnight in the selected zone.

The date uses the French Republican Calendar, introduced in 1793. The year begins at the autumnal equinox (~22 September). Each year has 12 months of exactly 30 days, plus 5 complementary days at year end (6 in a leap year). Years are numbered in Roman numerals from An I (1792).

Reading the date: dates are written as Weekday, Day Month An Year — e.g. Sextidi, 6 Ventôse An CCXXXIII means the 6th day of the month, in the 6th day of the décade (10-day week), in the month of Ventôse, year 233.
