Table of Contents :
Understanding military time can initially seem confusing, but it becomes straightforward once you grasp the basics. Military time, or the 24-hour clock system, is widely used in various sectors, including the military, aviation, and healthcare, because it eliminates the ambiguity associated with the 12-hour clock.

Why Use Military Time? 🤔
- Eliminates Confusion: Military time avoids any misunderstanding that could arise from AM and PM distinctions.
- Standardization: It provides a standardized way of communicating time, especially in situations where precision is critical, such as in the military and healthcare.
