what is 0045 military time?

0045 military time is a way to express 24-hour time. Military time is used by the United States Army, Navy and Air Force, as well as many other countries in the world to denote the time of day.

In military time, hours are numbered from 00 (midnight) to 23 (11pm). Minutes are always expressed in two digits, so 15 minutes past an even hour would be expressed as 0015. This means that 0045 military time is 45 minutes past midnight or 12:45am. All military times higher than 1200 will include a PM indicator (abbreviated P.M. or PM).

Military time can be used when discussing scheduled events or activities to avoid confusion between different formats of the 12-hour clock system. It is also helpful in many situations where minutes must be clearly understood, such as in aviation and medical fields where accuracy is vital. In contrast, times most commonly spoken in everyday life are shortened when spoken out loud and often do not include minutes or a clear indication of AM or PM. For example, "8 o'clock" could mean 8am or 8pm without further explanation which could lead to errors if not clarified by another person.

Military time requires no further clarification and everyone can easily deduce 12:45am simply by knowing that 0045 is 45 minutes past midnight and does not require any additional clarification for AM or PM – this makes it easier for all involved parties to understand exactly what time an event will take place without confusion due to different formats of expression from person to person.
