Time and Clock
The time and clock are different for different countries. If in country A there is a day then in country B there may be day or night or different time zone.
|
The sun rises in the morning.It rises in the east direction. |
 |
The sun sets in the evening.It sets in the west direction.. |
Between sunrise and sunset -----> Day time.
Between sunset and sunrise -----> Night.
There are two ways of writing time.
First way is use hours from 1 to 12.
So time before noon use -------> AM (ante meridiem)
and time after noon use -------> PM (post meridiem)
The second way is use time hours from 1 to 24, here the period is of 24 hours. So for PM, after 12 we count 13,14,15,...,24.
If there is 10 PM ------> 12 + 10 = 22:00
If there is 11 pm ------> 12+ 11 = 23:00
 |
Now here you can see the actual clock. There are two hands in it 1) hour hand 2) minute hand.
Hour Hand : It is shorter hand in a clock. It moves slowly.
Minute Hand : It is longer than the hour hand and it moves faster. |
If the hour hand is at 10 and minute hand is at 12 then we say that its 10 o'clock.
Examples :
Position of hour hand
11
9
6

Position of min hand

Practice
Write the time according to the position of hour and minute hand.
1) Hour hand at ---> 3 ; Minute hand at -----> 12
2) Hour hand at ---> 12 ; Minute hand at -----> 12
3) Hour hand at ---> 8 ; Minute hand at -----> 12
4) Hour hand at ---> 10 ; Minute hand at -----> 12
5) Hour hand at ---> 7 ; Minute hand at -----> 12
