What is 24-Hour Notation?

The 24-hour notation is a time-keeping system that divides the day into 24 hours, starting at midnight. This format is widely recognized and is particularly useful for eliminating confusion between morning and evening times. The hours are counted from 00:00 (midnight) to 23:59, with each hour represented by a two-digit number.

For example:

• 1:00 AM is represented as 01:00
• 1:00 PM is represented as 13:00
• 12:00 PM (noon) is represented as 12:00
• 12:00 AM (midnight) is represented as 00:00

History of 24-Hour Notation

The 24-hour clock has its roots in ancient civilizations, particularly the Egyptians, who divided the day into two 12-hour periods. This system was later adopted and modified by the Greeks and Romans. However, the widespread use of the 24-hour notation as we know it today began in the 19th century, particularly in the context of railway schedules.

The introduction of standardized time zones further popularized the 24-hour format, especially in transportation industries where precision was paramount. Today, many countries officially use the 24-hour format in public transportation timetables, military operations, and digital devices.

How to Read 24-Hour Notation

Reading the 24-hour notation is straightforward once you understand the basics. Here are some key points to keep in mind:

• Hours range from 00 to 23.
• Minutes are always written as two digits, ranging from 00 to 59.
• To convert to 12-hour time, subtract 12 from any hour greater than 12.
• For hours less than 12, simply add AM or PM based on whether it's before or after noon.
