Clock hands are the components of a clock that indicate the time by pointing to the numbers or markers on the clock face. They come in various shapes, sizes, and styles, depending on the design of the clock. The shortest hand on the clock indicates the hour. It moves slowly around the clock face, completing one revolution every 12 hours in a standard 12-hour clock. The longer hand on the clock indicates the minutes. It moves faster than the hour hand, completing one revolution every hour.
