The study of time and its measurement is called horology. This field encompasses the design, manufacture, and maintenance of timekeeping devices, such as clocks, watches, and sundials. Horologists—those who specialize in horology—explore the various methods of measuring time and the historical evolution of timekeeping technologies. Additionally, horology includes the study of time's philosophical and scientific aspects, such as time perception and its effects on daily life. From ancient civilizations to modern atomic clocks, horology reflects humanity's quest to understand and quantify the passage of time.
