Punch0100 Military Time
0100 hours is 1:00 AM standard time — said out loud, “zero one hundred hours.” Before noon, the numbers match the regular clock: 0100 is simply 1:00 AM.
01:00–01:59 by the quarter hour
| Military | Standard |
|---|---|
| 0100 | 1:00 AM |
| 0115 | 1:15 AM |
| 0130 | 1:30 AM |
| 0145 | 1:45 AM |
Minutes never convert — only the hour does. Any minute works the same way: 0107 is 1:07 AM, 0152 is 1:52 AM. For any other time, the military time converter takes both directions.
Where 0100 shows up
One in the morning, the deep end of a night shift. On a timecard, 0100 is unambiguous in a way “1:00” never is — nobody has to guess which side of noon you meant.
Common questions
What time is 0100 military time?
0100 hours is 1:00 AM standard time. Morning hours read the same on both clocks, so there's nothing to convert.
How do you say 0100 out loud?
“Zero one hundred” or “zero one hundred hours.” Whole hours are read as hundreds; with minutes you read both pairs — 0130 is “zero one thirty.”
Is 0100 AM or PM?
0100 is in the morning — any military time from 0000 through 1159 is AM.
