How to convert 0115 to standard time
- The hour digits are 01. Hours 01 to 11 are the same on both clocks — just drop the leading zero: 1.
- Put a colon before the minutes and add AM: 1:15 AM.
How to say 0115
| Style | How it sounds |
|---|---|
| Military (spoken) | “zero one fifteen hours” |
| Radio, digit by digit | “zero one one five” |
| Civilian | “quarter past one in the morning” |
| Written 24-hour | 01:15 or 0115 |
Off the hour, say the hour pair and then the minutes: 01 → “zero one”, 15 → “fifteen.” Adding “hours” at the end is standard in military speech but optional elsewhere.
0115 Zulu (UTC) in US time zones
Military and aviation schedules give times in Zulu — Coordinated Universal Time — so that everyone works from one clock. When a message says 0115Z, this is the local time across the United States:
| Time zone | Standard time | Daylight time |
|---|---|---|
| Eastern (EST / EDT) | 8:15 PM (previous day) — R | 9:15 PM (previous day) — Q |
| Central (CST / CDT) | 7:15 PM (previous day) — S | 8:15 PM (previous day) — R |
| Mountain (MST / MDT) | 6:15 PM (previous day) — T | 7:15 PM (previous day) — S |
| Pacific (PST / PDT) | 5:15 PM (previous day) — U | 6:15 PM (previous day) — T |
| Alaska (AKST / AKDT) | 4:15 PM (previous day) — V | 5:15 PM (previous day) — U |
| Hawaii (HST) | 3:15 PM (previous day) — W | No daylight time |
The letter after each time is that zone’s military time-zone letter: Eastern standard time is R (Romeo, UTC−5), so 0115Z is 2015R. Daylight time runs from the second Sunday in March to the first Sunday in November; Hawaii and most of Arizona stay on standard time all year.

0115 in everyday use
- 0115 falls in the overnight hours — the time of night shifts, red-eye flights and early deliveries. Writing it as 0115 instead of 1:15 AM removes any doubt about whether the morning or the evening is meant.
- On the day US clocks fall back in November, the hour from 0100 to 0159 happens twice, so 0115 occurs once in daylight time and again in standard time. Logs and timesheets kept in local time need a note for that night.
