Month

A month is a unit of time, used with calendars, which was first used and invented in Mesopotamia, as a natural period related to the motion of the Moon; month and Moon are cognates. The traditional concept arose with the cycle of moon phases; such months (lunations) are synodic months and last approximately 29.53 days. From excavated tally sticks, researchers have deduced that people counted days in relation to the Moon's phases as early as the Paleolithic age. Synodic months, based on the Moon's orbital period, are still the basis of many calendars today, and are used to divide the year.

Famous quotes containing the word month:

    January, month of empty pockets!... Let us endure this evil month, anxious as a theatrical producer’s forehead.
    Colette [Sidonie Gabrielle Colette] (1873–1954)

    The climate of Ohio is perfect, considered as the home of an ideal republican people. Climate has much to do with national character.... A climate which permits labor out-of-doors every month in the year and which requires industry to secure comfort—to provide food, shelter, clothing, fuel, etc.—is the very climate which secures the highest civilization.
    Rutherford Birchard Hayes (1822–1893)

    Until the Women’s Movement, it was commonplace to be told by an editor that he’d like to publish more of my poems, but he’d already published one by a woman that month ... this attitude was the rule rather than the exception, until the mid-sixties. Highest compliment was to be told, “You write like a man.”
    Maxine Kumin (b. 1925)
