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:

    Just the same as a month before,—
    The house and the trees,
    The barn’s brown gable, the vine by the door,—
    Nothing changed but the hives of bees.
    John Greenleaf Whittier (1807–1892)

    For myself I found that the occupation of a day-laborer was the most independent of any, especially as it required only thirty or forty days in a year to support one. The laborer’s day ends with the going down of the sun, and he is then free to devote himself to his chosen pursuit, independent of his labor; but his employer, who speculates from month to month, has no respite from one end of the year to the other.
    Henry David Thoreau (1817–1862)

    One non-revolutionary weekend is infinitely more bloody than a month of permanent revolution.
    Graffiti, School of Oriental Languages, London (1968)
