1500 Hours Is 3:00 PM in Regular Time

When using the times in the military, it is important to remember that the hours are not numbered in a standard 12 hour format. Hence, if you want to write 1PM at a restaurant, you should use a format with a colon between the hours and minutes. However, in some cases, it is appropriate to use a colon between the hours and minutes of 1500 military time. All times in military time format (24-hour time format) greater or equal than 1200 belong to PM hours. Military time is a method of measuring the time based on the full 24 hours of the day rather than two groups of 12 hours indicated by AM and PM. Using military time is the standard method used to indicate time for medication administration. The use of military time reduces potential confusion that may be caused by using AM and PM and also avoids potential duplication when giving scheduled medications. For example, instead of stating medication is due at 7 AM and 7 PM, it is documented on the medication administration record (MAR) as due at 0700 and 1900. See Figure 5.5[1] for an example clock and Table 5.3 for a military time conversion chart. One of the benefits of the 24-hour military time system is that it helps reduce confusion. Because everything operates on a 24-hour time scale, there is less chance of error than with a.m. This becomes even more important when military personnel discuss times and dates across time zones. The main differences are in the presentation and pronunciation. In particular, military time does not have a colon between the hours and minutes, and 24-hour time is not read or displayed with the word "hours". The question sometimes arises whether midnight is written as 2400 or 0000. Military and emergency services personnel refer to midnight both ways. However, digital watches and clocks that display time in a 24-hour format and computer equipment treat midnight as the start of a new day and express it as 0000.
