History of Clocks

The history of clocks spans a long period of time, with many different types of clocks appearing over the centuries. Not all historians agree on the history of the clock. The word clock was first used in the 14th century (about 700 years ago). It is derived from the Latin word for clock ('clocca'). The most aware historians know that 5000-6000 years ago, major civilizations in the Middle East and North Africa began to practice watchmaking, not just monthly and annual calendars. Little is known about how exactly these forms worked, or how time was deconstructed, but it is thought that the purpose was to maximize the use of available time to achieve more goals as populations increased. Perhaps such future periods were designed to benefit communities by allocating specific time periods for tasks.

Using the Sun

The first way to tell time is to watch the sun move across the sky. If the sun is directly above the sky, it is midday or noon. If the sun is close to the horizon, it is either early morning (sunrise) or late afternoon (sunset).
