What Is a 24 Hour Clock?

A 24-hour clock is a time format where the day runs from 00:00 to 23:59. Unlike the traditional 12-hour format that uses AM and PM, the 24-hour system avoids confusion by assigning unique hour values throughout the day.

Examples:

• 1:00 PM = 13:00
• 6:30 PM = 18:30
• Midnight = 00:00
• Noon = 12:00

This format is commonly used in:

• Military operations
• Airlines and airports
• Hospitals
• Railways
• International scheduling
• Digital systems
