0600 Military Time (6:00 AM)
0600 military time is 6:00 AM on the 12-hour clock. It is spoken as “zero six hundred” — often with “hours” added: “zero six hundred hours”.
0600 is the most culturally loaded time on the 24-hour clock: it is the stereotypical military morning. First formations, duty-day starts and wake-up calls cluster around it on many installations, and “up at oh-six-hundred” has escaped the military entirely to mean any unreasonably disciplined start to a day. The conversion is friendly, though — 0600 is simply 6:00 AM, one of the AM times whose digits still match the clock face.

Worked example: an 0600 departure with a report time
A travel itinerary written in 24-hour style says “depart 0600, report 0445”:
- 0600: hour 06 is below 12 → AM, drop the padding → 6:00 AM.
- 0445: hour 04 → AM again → 4:45 AM.
- The gap between them is what matters for your alarm: report time is 1 h 15 min before wheels-up.
Notice that converting a morning schedule never involves arithmetic on the hour — the work is just reading two-digit hours confidently. That is why morning times are the right place to start learning military time: you build the four-digit reading habit (first two digits hour, last two minutes) on times where a mistake is obvious, before the afternoon subtract-12 hours where it is not.
How to say 0600 out loud
Formally “zero six hundred”, almost always heard as “oh six hundred” in casual speech, with “hours” freely appended to either. The full pre-breakfast sequence runs “zero five thirty” (0530), “zero six hundred” (0600), “zero six fifteen” (0615) — leading zero voiced every time, “hundred” only on the exact hour. If you sound out the rows of the table below once, the pattern installs itself faster than any rule statement.

0600, 1800 and the half-day symmetry
0600 splits the AM half of the day exactly in the middle, which makes it a natural anchor point. Its evening mirror is 1800 — add 12 hours and the morning formation becomes the dinner hour. The symmetry is practical, not just pretty: people who work rotating 12-hour shifts (0600–1800, 1800–0600) live on exactly this pair, and seeing them as one mirrored unit makes the schedule legible at a glance. From the 0600 anchor, 0400 is two hours into yesterday’s sleep and 0800 is two hours into the working morning.
