Units of Time
There are different units of time.
Second, minute, hour, day, week, month and year are the units of time.
These have the following relations between each:
60 seconds = 1 minute
or
1 minute = 60 seconds
60 minutes = 1 hour
or
1 hour = 60 minutes
24 hours = 1 day (day + night)
7 days = 1 week
12 months = 1 year
52 weeks = 1 year
365 days or 366 days make a year
10 years make a decade
50 years make half century
100 years make a century
These are the relations between units of time.
So far we have studied the clocks having two hands – an hour
hand and a minute hand. Some clocks and watches have a thin and long hand which
moves faster than the other two hands called the second hand.
The second hand moves round the clock face in one minute. That is, it covers 60 small divisions in one minute. The time taken by it to move from one small division to the next is one second.
Thus, 60 seconds = 1 minute
Note: Minutes and seconds are symbolically represented with a single and double strokes at the top right of the numbers.
20 minutes = 20’, 20 seconds = 20”

We know that the measurement of time is read by a clock or a watch. Any clock or watch except a digital watch, has a dial. On the circular border of the dial of a watch or clock there are the
How to read a watch or a clock? The three figures will help us to read a clock. Hour hand indicates hours and Minute-hand indicates minutes.

We normally use 12-hour clock system. The hour hand of the clock goes round the dial twice a day (24 hours). Some departments like railways, Airlines, etc use 24-hour clock system because they do
