Q&A for How to Convert from 24 Hour to 12 Hour Time

And 00:20 means 12:20 at midnight.

That would be 3:15 p.m.

It could mean either. If it says 12:45 a.m., that means it's night, 45 minutes after midnight. If it says 12:45 p.m., it is the afternoon, 45 minutes after noon.

To convert to 24-hour time, if the time is AM, do nothing, whereas if it is PM, add 12:00 hours.

That would depend on the model, but you would normally simply turn the dial/press the button to add 12 hours.

Analog clocks are the ones with the second hand, minute hand and hour hand. They are the ones that you would usually see on walls. Digital clocks have the first number, a colon then another number like 12:15.

It is 2.10 p.m. or ten past two in the afternoon. Ten past two in the morning would be 02.10 or 02:10.

16:00 is 4:00PM in 24 hour time. If you are asking if it is night or day, it's around pre-evening or later afternoon.

When dealing with elapsed time between AM/PM and vice versa, you just have to work your way to midnight or noon, depending on whether the start time is AM or PM. In this case it is PM, so let's work our way to midnight. Midnight in our case will be represented by 24:00:00 (which is technically 0:00:00, but you should get the idea). So let's subtract 15:58:00 from 24:00:05. You cannot subtract 0 minutes from 58 minutes, so you have to borrow from the hours column. When you borrow an hour, you add 60 to the minutes column in the minuend. so 24:00:05 becomes 23:59:65. Now let's subtract the times: 23:59:65 - 15:58:00 = 8:01:05, add the remaining minute to get 8:02:05, the correct answer.

The minutes are read the same in a 24 or 12 hour clock. The only difference between the two clock styles is that you continue past 12 in the hours in the 24 hour style (13:00, 14:00, 15:00, and so on). The minute portion remains the same.

12:45 Hours is in the first twelve hours and forty five minutes of the day, so it would be 12:45 AM. Simply put, the 24 hour clock starts at zero at the start of a new day, and counts in sets of 60 minutes for 24 hours. Upon the final minute 23:59:59 (HH:MM:SS), we come back to 00:00:00 and the start of a new day.

The hours reset at 12 AM, so it would be 00:00. It doesn't go to 24:00, as by then it's another day.

Yes. It means ten minutes past midnight.

Because the decimal portions after the decimal point are the same, you can avoid subtracting the decimal portions entirely. So, 20-5=15.

03:00. (For AM times, just omit the AM unit. Between 12:00 and 12:59AM, change the hour to read 00. For PM, add 12 to the hour and omit the PM designation unit. For 12:00 and 12:59 PM, leave the hour alone and omit the designator.)

17:15. (Add 12 to the pm, but keep the minutes).

15:10 is 3:10 p.m. (If the hour number is greater than 12, subtract 12 from it).

1:20 pm is the same thing as 13:20.

It's 6:40 AM. Everything earlier than 1200 is AM. "Everything from 1200 to 2400 is PM. (2400 -- "24-hundred hours" -- is also known as 0000 -- "zero-hundred hours." They both refer to midnight.)
