Half Past an Hour
The hour hand takes one hour to move from one number to the next number. If it has gone from the number 1 to the number 2, it means one hour has passed.
The minute hand moves faster and it takes one hour to go around the clock. If it starts at 12 and goes around to get back to 12, it also means one hour has passed.
We learnt that, one hour is equal to 60 minutes. When one hour is divided into two, it is half an hour or 30 minutes. The minute hand points at 6. We say, 30 minutes past an hour or half past an hour.
