Converting 24-hour time to 12-hour time involves a few simple steps. Let’s break it down:
Identify the hour: Look at the first two digits of the 24-hour time. This represents the hour in the day.
Determine if it is AM or PM: If the hour is between 00:00 and 11:59, it is considered AM. If the hour is between 12:00 and 23:59, it is considered PM.
Subtract 12 (if necessary): If the hour is greater than 12, subtract 12 from it to convert it to the 12-hour format.
Combine the hour and minutes: Take the converted hour and combine it with the minutes of the original 24-hour time.
Add the AM or PM designation: Based on the determined AM or PM from step 2, add the appropriate designation to the converted time.
Let’s illustrate this process with an example:
Example: Converting 23:35 to 12-hour time.
The hour is 23.
Since 23 is greater than 12, we subtract 12 from it, resulting in 11.
The minutes remain the same, which is 35.
Combining the hour and minutes, we get 11:35.
Since the original time was in the PM range, the converted time will also be in PM. Therefore, the final converted time is 11:35 PM.
By following these steps, you can easily convert any given 24-hour time to its equivalent 12-hour format.
Examples of Converting Specific Times
To further solidify your understanding, let’s look at a few more examples of converting specific times from 24-hour to 12-hour format:

- The hour is 08.
- Since 08 is less than 12, no subtraction is needed.
- The minutes remain the same, which is 45.
- Combining the hour and minutes, we get 08:45.
- Since the original time was in the AM range, the converted time will also be in AM. Therefore, the final converted time is 08:45 AM.
- Example: Converting 18:20 to 12-hour time.
- The hour is 18.
- Since 18 is greater than 12, we subtract 12 from it, resulting in 6.
- The minutes remain the same, which is 20.
- Combining the hour and minutes, we get 6:20.
- Since the original time was in the PM range, the converted time will also be in PM. Therefore, the final converted time is 6:20 PM.
By practicing with various examples, you will become more comfortable and proficient in converting 24-hour time to 12-hour time.
