The hour hand is one of the two main hands on an analog clock, responsible for indicating the hour of the day. It is typically shorter and thicker than the minute hand, making it easily distinguishable. The hour hand moves around the clock face, completing one full rotation every twelve hours. As the hour hand moves, it points to the numbers on the clock, which represent the hours from 1 to 12. The position of the hour hand, along with the minute hand, helps people tell time accurately. Together, they provide a clear visual representation of the current time.
