� If minute hand is pointing at 6 and hour hand is in between 9 3
7 and 8, the time is read as “half past 7 (7:30)”. 8 7 6 5 4

Time in Hours and Minutes for all Positions of Minute Hand

� Note the position of the hour hand. 11 12 1

� Note the position of the minute hand. 10 2
� If minute hand is in the right half, multiply the minute hand 9 3
number by 5 and the time using ‘past’. 8 7 5 4

For example, In the given clock, 6

X hour hand is between 5 and 6. X minutes to read = 4 × 5 = 20.
X minute hand is at 4. (Right half) X Time is 20 minutes past 5 or 5:20.

� If the minute hand is in left half, count how many major divisions are left for
minute hand to reach 12. Multiply these major divisions by 5 and read the time
using ‘to’.

In the given clock, 10 11 12 1 2

X Hour hand is between 6 and 7. 9 3

X Minute hand is at 8. (Left half) 8 7 5 4
X There are 4 major divisions left for minute hand to reach 12. 6
So, minutes to read = 4 × 5 = 20.

X Time is 20 minutes to 7 or 6:40.
