How do I check 24-hour format?
Start with the number on your 24-hour clock, if it's between 13:00-23:59 take away twelve and you'll find the equivalent 12-hour number. If it's between 00:00 and 12:59 these are the same as a 12-hour clock and all in the morning/between noon and 1pm. 16:00 = 4:00 p.m. 21:00 = 9:15 p.m.
In the 24-hour clock format, each day runs from midnight to midnight and is divided into 24 hours. 24-Hour Time uses the numbers 00:00 (midnight) until 23:59 to tell the time. You don't need to use am / pm with a 24-Hour Clock, as afternoon is indicated by a number bigger than 12.
Add 12 to the hours between 1:00 and 11:59 PM and eliminate "PM." For the afternoon, evening, and night hours, simply add 12 to the 12-hour time to convert it to 24-hour time. Also, eliminate “PM.” That means that 2:57 PM would become 14:57 and 11:02 would become 23:02.
13 : 30 hours. 14 : 30 hours.
The easiest way to remember military time is: For any time prior to 10:00 AM, simply add a zero before the hour. For example: nine o'clock in the morning would be spoken as "zero nine hundred" and written as 0900. 10:00 AM would be 1000, "ten hundred" and so on.
| 24-Hour Clock Time Conversion Table | |
|---|---|
| 1 AM | 01:00 |
| 2 PM | 14:00 |
| 3 PM | 15:00 |
| 4 PM | 16:00 |
11:45 PM using 12-hour clock notation, 23:45 using 24-hour clock notation.
To convert time to a number of hours, multiply the time by 24, which is the number of hours in a day.
A usage example showing the 12 hour clock vs military time would be a time table showing 4:00 pm to 12:00 midnight. This would be written as 16:00 – 24:00. Another example highlighting the difference between the two would be to show that 10:15 am is written as 10:15 in military time but 2:30 pm is written as 14:30.
12:45 = 12:45 PM
12:45 on a 24-hour clock is is 12:45 PM on a 12-hour clock. This system is used throughout the world (not just the military) and leverages a 24-hour time clock rather than the 12-hour AM/PM system known to most English speaking countries.
What is 7.30 am in 24-hour format?
| 24-hour format | 12-hour format |
|---|---|
| 07:30 | 7:30 AM |
In 24-hour (military) time, 12:00am is equal to 0000 and is read as “0 hundred hours”.
0:30 = 12:30 AM. 0:55 = 12:55 AM.
6:00 AM = 0600
0600 (Zero Six Hundred Hours) military time on a 24-hour clock.
| am/pm | 24-hour |
|---|---|
| 7pm | 19:00 |
| 8pm | 20:00 |
| 9pm | 21:00 |
| 10pm | 22:00 |
Hence 6 PM can be read as 18:00 PM in 24 hour clock.
11:45 on a 24-hour clock is is 11:45 AM on a 12-hour clock.
05:40 PM using 12-hour clock notation, 17:40 using 24-hour clock notation.
08:52 PM using 12-hour clock notation, 20:52 using 24-hour clock notation.
To convert time into decimal format, you need to divide minutes by 60. The decimals are rounded, since decimal hours show only two decimal places. For example, 26 minutes divided by 60 equals 0.433333.
How do you write decimal hours?
' In decimal format one-half is expressed as '. 5'. So in decimal format this is expressed as 7.5 hours (7 and a half hours). When thought of in this way, it is not hard to understand that 7:30 (hours and minutes) = 7.5 decimal hours.
| Format | Time Segments | Description |
|---|---|---|
| 2 | HH:MM:SS XM | Time is based on a 12 hour system. AM or PM is given. Example: 02:18:23 PM |
| 3 | HH:MM | Time is based on a 24 hour system. Seconds are not given. Example: 14:18 |
| 4 | HH:MM XM | Time is based on a 12 hour system. Seconds are not given. AM or PM is given. Example: 02:18 PM |
This is called a sidereal day. On Earth, a sidereal day is almost exactly 23 hours and 56 minutes.
Midnight is called 24:00 and is used to mean the end of the day and 00:00 is used to mean the beginning of the day. For example, you would say "Tuesday at 24:00" and "Wednesday at 00:00" to mean exactly the same time.
| 24-hour format | 12-hour format |
|---|---|
| 04:30 | 4:30 AM |
Hence, 6:45 AM in 24-hour format will be 00:00 + 6:45 = 6:45.
| 24-hour format | 12-hour format |
|---|---|
| 01:30 | 1:30 AM |
07:45 = 7:45 AM
07:45 on a 24-hour clock is is 7:45 AM on a 12-hour clock. This system is used throughout the world (not just the military) and leverages a 24-hour time clock rather than the 12-hour AM/PM system known to most English speaking countries.
23:00 = 11:00 PM
23:00 on a 24-hour clock is is 11:00 PM on a 12-hour clock.
Hence 7:30 pm in 24-hour format will be, 12:00 + 7:30 = 19:30.
What is 7 30 in 24 hours?
Hence, 7:30 pm in 24-hour format will be, 12:00 + 7:30 = 19:30. Q.
Converting from a 24 Hour to a 12 Hour Clock
Starting from the first hour of the day (0:00 / midnight to 0:59), add 12 hours and AM to the time: 0:30 = 12:30 AM. 0:55 = 12:55 AM.
The 12-hour clock runs from 1am to noon and then from 1pm to midnight. The 24-hour clock runs from 00:00 (midnight) to 23:59.
- On your Android phone, open Settings, then: Android 9 select System > Date and Time. Android 8 select General Management > Date and Time. ...
- Select Set date, then the desired date on the calendar, and tap Done.
- Select Set time, then set the desired time on the clock, and tap Done.
A time of day is written in the 24-hour notation in the form hh:mm (for example 01:23) or hh:mm:ss (for example, 01:23:45), where hh (00 to 23) is the number of full hours that have passed since midnight, mm (00 to 59) is the number of full minutes that have passed since the last full hour, and ss (00 to 59) is the ...
Converting Times from 12-hour clock to 24-Hour clock
This means that 12:00am = 0000hrs, 1:00am = 0100hrs, etc. If the time is 1:00pm or greater, add 12 to the hours and that will get you the time in military time. For instance, 1:00pm + 12 = 1300hours, 2:00pm + 12 = 1400hrs and is pronounced 14 hundred hours.
