A clock is a device designed to measure, indicate, and maintain time. It is an essential tool for organizing daily activities and tracking the passage of hours, minutes, and seconds. Clocks come in various styles and formats, ranging from analog designs with hands and numerals to digital displays. They can be powered by mechanical movements, batteries, or smart technology, often integrating additional features such as alarms, timers, or connectivity to synchronize with global time systems. Beyond functionality, clocks are also decorative elements, crafted in materials like wood, metal, or glass, and designed to suit diverse aesthetics—from vintage and rustic to modern and minimalist.
