In Time

  • The Western zodiac has twelve signs, as does the Chinese zodiac.
  • The Chinese use a 12 year cycle for time-reckoning called Earthly Branches.
  • There are twenty-four hours in a day in all, with twelve hours for a half a day. The hours are numbered from one to twelve for both the ante meridiem (a.m.) half of the day and the post meridiem (p.m.) half of the day. 12:00 after a.m. and before p.m. (in the middle of the day) is midday or noon, and 12:00 after p.m. and before a.m. (in the middle of the night) is midnight. A new day is considered to start with the stroke of midnight. The basic units of time (60 seconds, 60 minutes, 24 hours) can all perfectly divide by twelve.

Famous quotes containing the word time:

    In the middle of the night, as indeed each time that we lay on the shore of a lake, we heard the voice of the loon, loud and distinct, from far over the lake. It is a very wild sound, quite in keeping with the place and the circumstances of the traveler, and very unlike the voice of a bird. I could lie awake for hours listening to it, it is so thrilling.
    Henry David Thoreau (1817–1862)

    The tumultuous populace of large cities are ever to be dreaded. Their indiscriminate violence prostrates for the time all public authority, and its consequences are sometimes extensive and terrible.
    George Washington (1732–1799)
