Marco Mastrofini

Marco Mastrofini (1763–1845), Italian priest, philosopher and mathematician.

History of work

In 1834 he offered to create the World and "eternal" calendar and has shown, that its invariance can be achieved only by application of so-called “special days”, i.e. such which would not be days of week or month. Marco Mastrofini offered to establish a calendar year in 364 days, i.e. in 52 full seven-day weeks, and to place 365th day of a year at the end of December of each year, considering it "special" or "out of week".

It was offered to enter one more «special» day in a leap year and to place it in the middle of a year, between the last day of June and the first day of July, or behind the first «special» day.

Influence on other calendars

His work significantly influenced the Armelin's calendar and calendar reform proposal by Auguste Comte in 1849.
