Time is a constant force in our lives, and measuring it in consistent units helps us organize our activities and understand the passage of events. Seconds, minutes, and hours are the foundational units of time, allowing us to coordinate everything from personal schedules to scientific experiments. The precise measurement of time is crucial for everything from history to technology.
