2300 Military Time Is 11:00 PM

By Sohail Manzoor · Updated

2300 = 11:00 PM

Twenty-three hundred

2300 in military time is 11:00 PM in standard time. Going the other way, 11 PM is written 2300. You say it “twenty-three hundred” or “twenty-three hundred hours”.

How to convert 2300 to standard time

The hour 23 is more than 12, so take 12 away. 23 minus 12 is 11. Keep the minutes and add PM, and you get 11:00 PM. To go back from 11 PM, add 12 to the hour. 11 plus 12 is 23, which gives 2300.

Where you see 2300

2300 is the usual start of a graveyard shift. The common pattern runs 2300 to 0700, which is 8 hours on the clock.
