How to use this military time converter
Type a time in the box — military (1830), 24-hour (18:30), or standard (6:30 PM) format all work.
Both equivalents appear instantly below the input.
Remember the shortcut: PM hours are the military hour minus 12; AM hours just gain a leading zero.

Frequently asked questions
What is 1830 in regular time?
6:30 PM. Subtract 12 from any military hour of 1300 or later: 18 − 12 = 6, so 1830 is 6:30 in the evening.
What is 6:30 PM in military time?
1830. Add 12 to PM hours: 6 + 12 = 18, and the minutes carry over unchanged.
Why does the military use 24-hour time?
It removes AM/PM ambiguity — a critical property for operations, aviation, healthcare, and logs where a 12-hour mix-up could be serious.
