How to say 1015
| Style | How it sounds |
|---|---|
| Military (spoken) | “ten fifteen hours” |
| Radio, digit by digit | “one zero one five” |
| Civilian | “quarter past ten in the morning” |
| Written 24-hour | 10:15 or 1015 |
Off the hour, say the hour pair and then the minutes: 10 → “ten”, 15 → “fifteen.” Adding “hours” at the end is standard in military speech but optional elsewhere.
1015 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 1015Z, this is the local time across the United States:
| Time zone | Standard time | Daylight time |
|---|---|---|
| Eastern (EST / EDT) | 5:15 AM — R | 6:15 AM — Q |
| Central (CST / CDT) | 4:15 AM — S | 5:15 AM — R |
| Mountain (MST / MDT) | 3:15 AM — T | 4:15 AM — S |
| Pacific (PST / PDT) | 2:15 AM — U | 3:15 AM — T |
| Alaska (AKST / AKDT) | 1:15 AM — V | 2:15 AM — U |
| Hawaii (HST) | 12:15 AM — 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 1015Z is 0515R. 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.
