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:

    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)

    Let us lie down once more by the breathing side
    Of Ocean, where our live forefathers sleep
    As if the Known Sea still were a month wide—
    Atlantis howls but is no longer steep!
    Allen Tate (1899–1979)

    It makes little sense to spend a month teaching decimal fractions to fourth-grade pupils when they can be taught in a week, and better understood and retained, by sixth-grade students. Child-centeredness does not mean lack of rigor or standards; it does mean finding the best match between curricula and children’s developing interests and abilities.
    David Elkind (20th century)
