A wall clock is a timekeeping device designed to be mounted on a wall. It typically features a circular face with numbers or markers that indicate the hours and minutes. Most wall clocks use either analog or digital displays, with analog clocks using rotating hands to show the time, while digital clocks display the time in numerical form. Wall clocks can be powered by batteries, electricity, or even mechanical winding. They come in various styles, sizes, and materials, making them both functional and decorative. Many people use wall clocks in homes, offices, and public spaces to help keep track of time throughout the day.
