The Concept of Clocks

A Clock is a device which shows Time. It essentially consists of two hands – an hour hand and a minute hand. The minute hand is longer than the hour hand. For simplicity, we will not consider the third hand – the second hand – which is also present in many clocks and watches.

Conventionally clocks are circular in shape but we can now find them in other different shapes too. Irrespective of the shape of the dial of the clock, the tips of their hands – hour as well as minute – describe a circular path.

The circumference of this circular path is divided into 12 equal parts, called Hour spaces. Each hour space is further divided into 5 equal parts called Minute Spaces.

Thus the complete circumference is divided into 12 × 5 = 60 equal minute spaces.
