Clock Face - Reading A Modern Clock Face

Reading A Modern Clock Face

Most modern clocks have the numbers 1 through 12 printed at equally spaced intervals around the periphery of the face with the 12 at the top, indicating the hour, and on many models, sixty dots or lines evenly spaced in a ring around the outside of the dial, indicating minutes and seconds. The time is read by observing the placement of several "hands" which emanate from the centre of the dial:

  • A short thick "hour" hand;
  • A long, thinner "minute" hand; and on some models,
  • A very thin "sweep" seconds hand

All the hands continuously rotate around the dial in a 'clockwise' direction - in the direction of increasing numbers.

  • The sweep hand moves relatively quickly, taking a full minute (sixty seconds) to make a complete rotation from '12 to 12.' For every rotation of the sweep hand, the minute hand will move from one minute mark to the next.
  • The minute hand rotates more slowly around the dial, it takes one hour (sixty minutes) to make a complete rotation from '12 to 12.' For every rotation of the minute hand, the hour hand will move from one hour mark to the next.
  • The hour hand moves slowest of all, taking twelve hours (half a day) to make a complete rotation. It starts from '12' at midnight, makes one rotation until it is pointing at '12' again at noon, then makes another rotation until it is pointing at '12' again at midnight of the next night.

In the example picture, showing a two handed clock, the minute hand is on "14" minutes and the hour hand is moving from '12' to '1' - this indicates a time of 12:14.

Famous quotes containing the words reading a, reading, modern, clock and/or face:

    “People who have been made to suffer by certain things cannot be reminded of them without a horror which paralyses every other pleasure, even that to be found in reading a story.”
    —Stendhal [Marie Henri Beyle] (1783–1842)

    “When committees gather, each member is necessarily an actor, uncontrollably acting out the part of himself, reading the lines that identify him, asserting his identity.... We are designed, coded, it seems, to place the highest priority on being individuals, and we must do this first, at whatever cost, even if it means disability for the group.”
    —Lewis Thomas (b. 1913)

    “A more problematic example is the parallel between the increasingly abstract and insubstantial picture of the physical universe which modern physics has given us and the popularity of abstract and non-representational forms of art and poetry. In each case the representation of reality is increasingly removed from the picture which is immediately presented to us by our senses.”
    —Harvey Brooks (b. 1915)

    “By putting forward the hands of the clock you shall not advance the hour.”
    —Victor Hugo (1802–1885)

    “Go through the gates with closed eyes.
    Stand erect and let your black face front the west.”
    —Arna Bontemps (1902–1973)
