Question

Why do we need to measure time?

Answer 1

All our activities depend on time. On a day to day basis, we need to perform and manage various activities which require the measurement of time. For example, to know the duration of a journey, to meet the schedules in work, to know whether its day or night, to know the heartbeat, to know the amount of time taken by the computer to perform an operation etc. Hence it is very important to measure the time.
