Note 55 — Chapter XXII · THE METRIC SYSTEM
Reading edition
In this Positivist Calendar the saints of the old calendar and the agricultural produce of the revolutionary calendars are replaced by great men and women; typical great men, from Moses and Homer to Descartes and Bichat, giving their names to the 13 months, each of 28 days. There is an extra day at the end of the year, and two extra days in leap-year. This system has the advantage of the 7th, 14th, 21st and 28th of the month always falling on the same day of the week.
The Positivist era dates from 1789; and the followers of Auguste Comte, in England, France and elsewhere, thus date 1911 as the ‘year 123 of the Great Crisis.’
