One hour is a unit of time that equals 60 minutes. It is commonly used in everyday life to measure durations, such as how long a meeting lasts or how long it takes to cook a meal. The concept of an hour is part of the larger system of timekeeping, which includes seconds, minutes, and days. In many cultures, an hour is divided into two halves, known as half-hours, and can be further divided into quarters of 15 minutes each. Clocks and watches are typically used to track hours, helping people organize their schedules and manage their time effectively.
