Formula: Midnight 12 AM = 00; 1 AM-11 AM stay the same; 12 PM = 12; 1 PM-11 PM add 12. Reverse for 24 to 12.
- You entered 2:30 PM.
- Hour: 2 PM, add 12 = 14.
- Minutes carry over unchanged: 30.
- 24-hour: 14:30 = 1430. 12-hour: 2:30 PM.
Result: 2:30 PM = 1430 (fourteen thirty hours)
How 12-hour time converts to military time
12 AM = 00
1 AM to 11 AM = same
12 PM = 12
1 PM to 11 PM = hour + 12
military = HH followed by MM
Military time numbers the hours 00 to 23 and drops AM and PM. Minutes never change, so only the hour converts, written as four digits with no colon: 1430.
In the morning the hour stays the same, except 12:00 AM becomes 00 (12:30 AM is 0030). Noon stays 12, so 12:00 PM is 1200. For 1 PM to 11 PM add 12: 1:05 PM is 1305 and 11:59 PM is 2359. To go back, 0 becomes 12 AM, 1 to 11 stay AM, 12 is PM, and 13 to 23 subtract 12.

0000 versus 2400
Both are 12:00 AM on a clock. 0000 is the first instant of a new day and 2400 is the last instant of the day that is ending. This converter accepts 2400 and shows it as 12:00 AM; any other 24 hour, such as 2401, is rejected.
How military time is spoken
Read the hour pair, then the minute pair, then "hours": 1430 is "fourteen thirty hours". Exact hours use "hundred": 1300 is "thirteen hundred hours". Hours under ten keep a "zero": 0830 is "zero eight thirty hours". A trailing Z, as in 1430Z, labels Zulu (UTC) time but does not change the digits.

2:30 PM is 1430. Add 12 to the hour (2 + 12 = 14) and keep the minutes, then say "fourteen thirty hours".
Is midnight 0000 or 2400?
Both are used. 0000 is the start of a day and 2400 is the end of the previous day. They are the same clock time, 12:00 AM, so this converter accepts either.

No. It only changes the format of a single time. A Z suffix marks the time as Zulu (UTC) but the digits stay as you typed them.
