Clock notation is a method used to describe the position of hands on a clock face, typically in relation to the hours and minutes. It is often represented using numbers from 1 to 12, corresponding to the hours, with the minute hand indicating the number of minutes past the hour. For example, 3:00 means the hour hand is on 3, and the minute hand is on 12. This notation is commonly used in various fields, including timekeeping, scheduling, and navigation. It provides a simple way to communicate time without needing to specify AM or PM, making it useful in both casual and formal contexts.
