We tell time by looking at the hands of a clock. 

At the hour, the long hand (minute hand) points to 12. The short hand points to the hour.

At half past, the long hand will point to the six and the short hand will point to just after the hour.

Example 1 => 6 o’clock (or 6 =>00).

Example 2 => Half past 6 (or 6 =>30).

Example 3 => 2 o’clock (or 2 =>00).

Example 4 => Half past 11 (or 11 =>30).

Now try a few practice questions!
