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:

    In man, the shedding of blood is always associated with injury, disease, or death. Only the female half of humanity was seen to have the magical ability to bleed profusely and still rise phoenix-like each month from the gore.
    Estelle R. Ramey (b. 1917)

    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)

    The slanders poured down like Niagara. If you take into consideration the setting—the war and the revolution—and the character of the accused—revolutionary leaders of millions who were conducting their party to the sovereign power—you can say without exaggeration that July 1917 was the month of the most gigantic slander in world history.
    Leon Trotsky (1879–1940)
