The revolutionary system was designed in part to remove all religious and royalist influences from the calendar, and was part of a larger attempt at decimalisation in France which also included decimal time of day, decimalisation of currency, and metrication. It was used in government records in France and other areas under French rule, including Belgium , Luxembourg , and parts of the Netherlands , Germany , Switzerland , Malta , and Italy. The months of September [meaning "the seventh"] through December [meaning "the tenth"] are already numeric names, although their meanings do not match their positions in either the Julian or the Gregorian calendar since the Romans added the months January and February to the original ten-month March to December year of King Romulus. Individual days were assigned, instead of to the traditional saints, to people noteworthy for mostly secular achievements; 25 December is assigned to both Jesus and Newton. Later editions of the almanac would switch to the Republican Calendar.

Mathemagicians would never dream of doing that, of course. At worst, we might sneak in a few little fibs. See if you can catch the hidden meaning in his words as he performs the Little Fibs trick.

The calendar was the predominant calendar in the Roman world, most of Europe, and in European settlements in the Americas and elsewhere, until it was gradually replaced by the Gregorian calendar , promulgated in by Pope Gregory XIII. The Julian calendar is still used in parts of the Eastern Orthodox Church , in parts of Oriental Orthodoxy and Anabaptism , [2] as well as by the Berbers. During the 20th and 21st centuries, a date according to the Julian calendar is 13 days earlier than behind its corresponding Gregorian date. The ordinary year in the previous Roman calendar consisted of 12 months, for a total of days. In addition, a or day intercalary month , the Mensis Intercalaris , was sometimes inserted between February and March.
