How to Convert 0100
0100 falls in the morning half of the 24-hour clock, so the rule is: the hour matches standard time — just add AM.
1 = 1 → 1:00 AM — morning hours match directly (the minutes, 0, stay exactly the same).
Going the other way: 1:00 AM = 0100 — drop the AM and pad single-digit hours with a leading zero. Or skip the math — type 0100 into the military time converter and convert any time instantly on the home page.

When You'll See 0100
The small hours. Overnight crews — hospital night nurses, dispatchers, bakers starting early — see 0100 (1:00 AM) on their logs and handoff notes. Flights departing around 0100 are the first red-eyes of the morning.
To say it out loud: "zero one hundred hours." Whole hours always take the "hundred" wording.
