2045 military time is 8:45 PM. In colon-based 24-hour notation, the same time is 20:45. To convert it, subtract 12 from the hour 20: 20 − 12 = 8; the 45 minutes stay unchanged.
The direct answer is 2045 = 20:45 = 8:45 PM. Searches written as “20 45 military time”, “8:45pm military time” or “8 45 pm military time” all refer to this same time of day.
Because the hour 20 is greater than 12, subtract 12 from the hour and keep the minutes unchanged.

Reverse check: 8:45 PM → 20:45 → 2045 ✓
These three forms identify the same time of day. The difference is presentation: military-style notation, a colon-based 24-hour display, and standard 12-hour AM/PM notation.
The values are equivalent, but the formats are not identical. Searches such as “what is 2045 in military time”, “20:45 military time” and “8:45 PM in military time” all resolve to the same clock-time relationship.
| Format | How the Time Appears | Meaning |
|---|---|---|
| Military-style | 2045 | Four digits with no colon. |
| 24-hour clock | 20:45 | The same hour and minutes with a colon. |
| 12-hour standard | 8:45 PM | Uses PM to identify the evening period. |
U.S. Navy correspondence guidance used by the master template describes military time as four digits based on the 24-hour clock, with the hour represented by the first two digits and the minutes by the final two digits, without a colon.
That means 20:45 is the colon-based 24-hour display, while 2045 is the corresponding four-digit military-style notation. Both equal 8:45 PM.
2045 is commonly read as “twenty forty-five.” The standard English spelling is forty-five. Because this is not a whole hour, the spoken form reads the hour followed by the minute value.
The U.S. Army Center of Military History guidance used by the template notes that adding the word hours is not necessary when expressing time connected with military activity. So “twenty forty-five” is concise; “twenty forty-five hours” may also be heard in some contexts.
2045 is PM. It equals 8:45 PM, an evening time. In ordinary language, 8:45 PM is also quarter to 9 PM.
The U.S. Navy source used by the master template defines military time as a four-digit expression based on the 24-hour clock, with hour digits first, minute digits last, and no colon between them. Applying that notation to 20:45 gives 2045.
The U.S. Army Center of Military History guidance likewise treats time connected with military activity on a 24-hour basis and notes that adding the word hours is not necessary. These general rules support the notation and pronunciation conventions applied here.
By itself, 2045 identifies the time of day, not a geographic time zone. A zone letter, abbreviation or other time-zone reference is separate information.
For Zulu letters and military-zone notation, use the dedicated Military Time Zones guide. For civilian geographic time-zone conversion, use the CalendarHours Time Zones hub.
The official CalendarHours SILO links 2045 directly to the approved neighboring values 2030 and 2100. The 2015 and 2115 pages add useful surrounding context without generating an indexable page for every minute.
Use the specific 2045 page for this equivalence, and move to a hub when your task becomes broader.
Converting 2045 ↔ 8:45 PM is a format conversion. If you need to add time, subtract time, or measure a duration from 2045, that is a separate arithmetic intent.
CalendarHours calculates this equivalence directly from the 24-hour clock. For a PM hour above 12, subtract 12 from the hour and leave the minutes unchanged: 20 − 12 = 8, so 20:45 = 8:45 PM. Four-digit military-style presentation removes the colon: 20:45 → 2045.
