Pentecontad Calendar

The Pentecontad Calendar is a unique agricultural calendar system thought to be of Amorite origin in which the year is broken down into seven periods of fifty days ( total of 350 days ), with an annual supplement of fifteen or sixteen days. Identified and reconstructed by Hildegaard and Julius Lewy in the 1940s, the calendar's use dates back to at least the 3rd millennium BCE in western Mesopotamia and surrounding areas. Used well into the modern age, forms of it have been found in Nestorianism and among the fellaheen of modern Palestine.

Famous quotes containing the word calendar:

    To divide one’s life by years is of course to tumble into a trap set by our own arithmetic. The calendar consents to carry on its dull wall-existence by the arbitrary timetables we have drawn up in consultation with those permanent commuters, Earth and Sun. But we, unlike trees, need grow no annual rings.
    Clifton Fadiman (b. 1904)
