The conversion rule
Before 1300: read as-is (0930 = 9:30 AM)
1300 and later: subtract 12 from the hour (1730 → 5:30 PM)
Going the other way, add 12 to any PM hour except 12 PM itself, and write
12 AM as 00. Minutes never change.
Frequently asked questions
What is 1730 in regular time?
1730 is 5:30 PM. For any military time of 1300 or later, subtract 12 from the hour: 17 − 12 = 5, so 1730 becomes 5:30 PM. Times before 1200 read the same in both systems (0930 = 9:30 AM).
How do you read military time?
Military time uses a 24-hour clock written as four digits with no colon: the first two digits are the hour (00–23), the last two are the minutes. 0000–1159 is the morning (AM), 1200–2359 is afternoon and evening (PM). To convert 1300 or later to a 12-hour time, subtract 12 from the hour. Whole hours are spoken as "hundred" — 0800 is "zero eight hundred."
Is midnight 0000 or 2400 in military time?
Both are used, with a convention: 0000 marks the start of a day and 2400 marks the end of the previous day. So "Friday 2400" and "Saturday 0000" are the same instant. Most digital systems, timesheets and the US military standard prefer 0000.
What is 12:00 AM and 12:00 PM in military time?
12:00 AM (midnight) is 0000 and 12:00 PM (noon) is 1200. The 12-hour clock is most confusing exactly at these two points, which is why hospitals, the military and transit schedules use the 24-hour clock.
Why do timesheets use military time?
A 24-hour clock removes AM/PM ambiguity, which matters for overnight shifts: 10:00 PM to 6:00 AM is unmistakably 2200 to 0600. Many time clocks also export 24-hour times because payroll math is simpler without AM/PM parsing.
