What Time Is 20 In Military Time? This is a common question, and at WHAT.EDU.VN, we’re here to provide you with a clear and comprehensive answer. We aim to simplify time conversions and explore the practical applications of military time, also known as the 24-hour clock, ensuring you grasp this concept effortlessly. Delve into time conversion charts, universal time zones, and other tools to enhance your understanding.
1. Understanding Military Time: The Basics
Military time, often called the 24-hour clock, is a timekeeping system that uses all 24 hours of the day instead of dividing it into two 12-hour periods (AM and PM). This system is widely used in the military, aviation, healthcare, and other fields where clarity and precision are crucial. Understanding the basics of military time can help prevent confusion and ensure accurate communication.
1.1. Why Use Military Time?
Military time eliminates ambiguity. For instance, saying “8 PM” can be confusing; is it 8:00 in the evening or the morning? In military time, 8 PM is clearly stated as 20:00 (pronounced “twenty hundred hours”). This clarity is essential in fields where mistakes can have serious consequences.
1.2. Converting PM to Military Time
To convert PM time to military time, simply add 12 to the hour. For example:
- 1 PM becomes 13:00
- 2 PM becomes 14:00
- 6 PM becomes 18:00
- 8 PM becomes 20:00
- 11 PM becomes 23:00
This simple addition removes any ambiguity and provides a clear, concise time.
1.3. Converting AM to Military Time
Converting AM time to military time is even easier. For hours 1 AM to 9 AM, simply add a leading zero. For example:
- 1 AM becomes 01:00
- 6 AM becomes 06:00
- 9 AM becomes 09:00
For 10 AM to 12 PM (noon), the military time is the same as the standard time. For example:
- 10 AM remains 10:00
- 12 PM (noon) remains 12:00
1.4. How to Pronounce Military Time
Pronouncing military time correctly is important for clear communication. Here are a few tips:
- Read the Numbers Directly: For example, 15:00 is pronounced “fifteen hundred hours.”
- Use “Hundred Hours”: The term “hundred hours” is typically added to the end of the time.
- Leading Zeros: Leading zeros are pronounced. For example, 05:00 is pronounced “zero five hundred hours.”
1.5. Common Misconceptions About Military Time
One common misconception is that military time is only used by the military. While the military does use it extensively, many other industries and organizations also rely on this system for its clarity and precision. Another misconception is that it’s difficult to learn. Once you understand the basic principles, converting between standard time and military time becomes second nature.
2. What Time Is 20:00 in Standard Time?
The answer to the initial question, “What time is 20 in military time?” is that 20:00 corresponds to 8 PM in standard time. To arrive at this answer, subtract 12 from 20. This conversion is straightforward and consistent, making military time easy to understand and use.
