Marco Mastrofini

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

History of work

In 1834 Mastrofini offered to create for the world an "eternal" calendar, and demonstrated that its invariance can be achieved only by application of special intercalary days that would belong to any week or month. He offered to establish a calendar year of 364 days split into 52 seven-day weeks, and to place the 365th day of each year at the end of December, considering it special or out of week.

He planned 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 following 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.

gollark: If you're writing a thing you probably have a decent idea of the problem domain involved and what's going on, and just have to work out how to express that in code.
gollark: What I'm saying is that reading things and understanding them can be harder than writing them sometimes.
gollark: Yes. It's not unique to Haskell.
gollark: For example, if I was doing Haskell, I could write everything awfully in `IO` and make it very comprehensible to a C user, or I could write it in some crazy pointfree way which I don't understand 5 seconds after writing it.
gollark: e.g. you probably wouldn't just go for C, if you wanted to avoid being caught.
