How to Read Military Time
Two rules, one habit — and the pronunciation that makes you sound like you've always used it.
Practice: read it out loud
The two rules
Rule 1 — morning is easy: 0100–0900 is 1–9 AM. Drop the leading zero when speaking: 0700 = “seven hundred hours” (people say “oh seven hundred” casually — both are understood).
Rule 2 — afternoon, subtract 12: 1300 = 1 PM, 1800 = 6 PM, 2300 = 11 PM. Reading “eighteen hundred” and thinking “6 PM” takes about a week of practice.
Special cases
0000 / 2400: midnight — 0000 starts a day, 2400 ends one. 1200: noon, the pivot. Minutes: spoken as-is — 0930 = “zero nine thirty hours”; single-digit minutes get each digit: 0005 = “zero zero zero five hours.”
Why it exists
No AM/PM ambiguity, ever. A medication log that says 0800 can't be misread as evening; a flight at 1630 can't be boarded 12 hours late. The military standardized it, and hospitals, airlines, logistics, and emergency services kept it for the same reason — mistakes in those worlds cost more than a syllable of awkwardness.
Drill above until it's boring, print the chart for the wall, and convert anything with the converter.
