The small hand on a clock that shows the hours.
It goes once around the clock every 12 hours (half a day).
Example: in the clock shown, the hour hand is just past the "8" so you know the time is just past "8 o'clock".
The large hand is the minute hand and it shows that it is 22 past the hour, so it is 22 past 8.
