How to convert 2345 to standard time

- Keep the minutes (45), insert a colon and add PM: 11:45 PM.
How to say 2345
| Style | How it sounds |
|---|---|
| Military (spoken) | “twenty-three forty-five hours” |
| Radio, digit by digit | “two three four five” |
| Civilian | “quarter to midnight” |
| Written 24-hour | 23:45 or 2345 |
Off the hour, say the hour pair and then the minutes: 23 → “twenty-three”, 45 → “forty-five.” Adding “hours” at the end is standard in military speech but optional elsewhere.
2345 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 2345Z, this is the local time across the United States:
| Time zone | Standard time | Daylight time |
|---|---|---|
| Eastern (EST / EDT) | 6:45 PM — R | 7:45 PM — Q |
| Central (CST / CDT) | 5:45 PM — S | 6:45 PM — R |
| Mountain (MST / MDT) | 4:45 PM — T | 5:45 PM — S |
| Pacific (PST / PDT) | 3:45 PM — U | 4:45 PM — T |
| Alaska (AKST / AKDT) | 2:45 PM — V | 3:45 PM — U |
| Hawaii (HST) | 1:45 PM — 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 2345Z is 1845R. 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.
