How to convert 0445 to standard time

- Put a colon before the minutes and add AM: 4:45 AM.
How to say 0445
| Style | How it sounds |
|---|---|
| Military (spoken) | “zero four forty-five hours” |
| Radio, digit by digit | “zero four four five” |
| Civilian | “quarter to five in the morning” |
| Written 24-hour | 04:45 or 0445 |
Off the hour, say the hour pair and then the minutes: 04 → “zero four”, 45 → “forty-five.” Adding “hours” at the end is standard in military speech but optional elsewhere.
0445 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 0445Z, this is the local time across the United States:
| Time zone | Standard time | Daylight time |
|---|---|---|
| Eastern (EST / EDT) | 11:45 PM (previous day) — R | 12:45 AM — Q |
| Central (CST / CDT) | 10:45 PM (previous day) — S | 11:45 PM (previous day) — R |
| Mountain (MST / MDT) | 9:45 PM (previous day) — T | 10:45 PM (previous day) — S |
| Pacific (PST / PDT) | 8:45 PM (previous day) — U | 9:45 PM (previous day) — T |
| Alaska (AKST / AKDT) | 7:45 PM (previous day) — V | 8:45 PM (previous day) — U |
| Hawaii (HST) | 6:45 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 0445Z is 2345R. 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.
