How to convert 1315 to standard time
- The hour digits are 13, which is past noon. Subtract 12 from the hour: 13 − 12 = 1.
- Keep the minutes (15), insert a colon and add PM: 1:15 PM.
How to say 1315
| Style | How it sounds |
|---|---|
| Military (spoken) | “thirteen fifteen hours” |
| Radio, digit by digit | “one three one five” |
| Civilian | “quarter past one in the afternoon” |
| Written 24-hour | 13:15 or 1315 |
Off the hour, say the hour pair and then the minutes: 13 → “thirteen”, 15 → “fifteen.” Adding “hours” at the end is standard in military speech but optional elsewhere.
1315 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 1315Z, this is the local time across the United States:
| Time zone | Standard time | Daylight time |
|---|---|---|
| Eastern (EST / EDT) | 8:15 AM — R | 9:15 AM — Q |
| Central (CST / CDT) | 7:15 AM — S | 8:15 AM — R |
| Mountain (MST / MDT) | 6:15 AM — T | 7:15 AM — S |
| Pacific (PST / PDT) | 5:15 AM — U | 6:15 AM — T |
| Alaska (AKST / AKDT) | 4:15 AM — V | 5:15 AM — U |
| Hawaii (HST) | 3:15 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 1315Z is 0815R. 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.

1315 in everyday use
- From 1300 on, the hour digits run past 12. A quick trick for 1300 to 1959 is to take 2 away from the second digit: 13 → 1, so 1315 is 1:15 PM.
- The classic misreading is to drop the leading 1 and read 1315 as 3:15 — that would put the time two hours late.
