This document explains how to tell time on an analog clock. It discusses that clocks have two hands - an hour hand and a minute hand. The hour hand is shorter and points to the hour, while the minute hand is longer and points to the minutes. When the minute hand points to 12, it is showing a full hour or 'o'clock'. It provides examples of different times on clocks and explains that there are 60 minutes in an hour because the numbers on a clock represent increments of 5 minutes and there are 12 numbers on a clock face.
