Understanding Hours

Hours are a unit of time that measure the duration of an event or the interval between two points in time. The concept of hours is essential for understanding the passage of time and for scheduling daily activities.

Key Concepts:

1. 60 Minutes: An hour is divided into 60 minutes. This means that 1 hour = 60 minutes.
2. AM and PM: The 12-hour clock system divides the day into two 12-hour periods. "AM" stands for ante meridiem (before noon) and "PM" stands for post meridiem (after noon).
3. 24-Hour Clock: The 24-hour clock system uses the numbers 00:00 to 23:59 to represent the hours and minutes of the day. This system is commonly used in military, aviation, and international contexts.
