In this article we are going to discuss the 12 hour clock now if you’re wondering what exactly do I mean by 12 hour clock?
12:00 hour clock is the clock that repeat’s the period of 12 hours Two times a day. Now if we dive deep in we can see that 12 hour clock discriminates day and night time by adding am and pm with the digits. 12:00 hour clock is in the use Of common people.
Now As for talking about 24 hour clock that is our standard time showing clock. We also call the 24 hour clock as military clock or army clock. The reason of why 24 hour clock is used as Standard Time showing Clock is because it provides accuracy and goes in the floor from 12 to 24 hours completing the 24 hour time cycle.
This was the overview of 12 hour clock, and a comparative introduction of 24 hour clock. Now let’s find out the conversion techniques, and charts.
12 Hour Clock Into 24 Hour Clock
There are two clocks that show us time and both have different aspects and features. As explained earlier 24 hour clock completes the total cycle of 24 digits but 12 hour clock repeats the cycle of 12 hours for 2 times in 25 hours. Now if you are confused that how with the same cycle does this clock discriminates night and day, then let me make it easy for you to understand. In this clock am and pm, is added with the digits showing time. For instance the clock has 1 am, and then 1 pm. Now (am) is used to show morning time or mid night. While pm shows after noon, evening and night.
12 Hour Clock Format
You may have heard the am and pm a lot, as we use am/pm clock in our daily routine to keep up with the time schedule. To go deep into etymology, we were able to track that am came from Latin word. Which is (ante meridiem) that has the meaning of “before mid-day”. As the sun at that time did has not crossed the meridian line. While “pm” means (post meridiem) that means after the mid-day. As The sun has now crossed the meridian line. At the time of exactly 12 in the noon or you can say 12 pm, the sun is at its highest point in the sky. And that is why it I called 12 noon and not pm. Same is the case when we talk about 12 in the midnight but not as am. Hope now it is clear to you how can we use am and pm and how 12 digit in this clock is an exception.
Let’s Convert 12 Hour Clock Into 24 Hour Clock
Although 24 hour clock is the standard clock, but use of 12 hour clock is more common especially in the civil communities and in Latin America. The list doesn’t stop here, this clock has a lot more popularity around in other English speaking countries too. Now the question here arises is that why to you need to learn the conversion of both these clocks. It can have more than one reasons but one of the reasons is for work and business purpose. While you are into business you will come across many people from different backgrounds, and there you might face the challenge of them using and understanding only one of these clocks and you using the other one. So now let’s begin to learn them and the conversion too.
| 24 hour Clock | 12 hour Clock | 24 hour Clock | 12 hour Clock |
| 00:00 | 12 am | 12:00 | 12 noon |
| 01:00 | 01 am | 13:00 | 01 pm |
| 02:00 | 02 am | 14:00 | 02 pm |
| 03:00 | 03 am | 15:00 | 03 pm |
| 04:00 | 04 am | 16:00 | 04 pm |
| 05:00 | 05 am | 17:00 | 05 pm |
| 06:00 | 06 am | 18:00 | 06 pm |
| 07:00 | 07 am | 19:00 | 07 pm |
| 08:00 | 08 am | 20:00 | 08 pm |
| 09:00 | 09 am | 21:00 | 09 pm |
| 10:00 | 10 am | 22:00 | 10 pm |
| 11:00 | 11 am | 23:00 | 11 pm |
| 24:00 | 12 mid night |
While converting 12 hour clock into 24 hour Clock, remember that am and pm clock splits into 2 periods and one period consists of 12 hours to be exact. The first period of 12 hours runs from mid night to noon while the second cycle runs from noon to mid night. Thus the first one is known as am cycle and the other is pm cycle. This is the most simple explanation you’ll ever find.
