Quick answer: 2300 military time is 11:00 PM in regular time.
See 2300 on a duty roster, a medical chart, or a clock? That means eleven o’clock at night. One hour before midnight.
Here’s the quick math and where you’ll actually encounter this time.
How to Convert 2300 to Regular Time
For any military time over 1200, subtract 12.
23 minus 12 = 11
So 2300 is 11:00 PM.
Fun fact: 2300 is the last “normal” hour in military time. After this comes 0000 (midnight), and the whole cycle starts over.
What About Minutes?
The minutes are always the same in both systems. Only the hour needs converting.
2330 is 11:30 PM. 2315 is 11:15 PM. 2345 is 11:45 PM.
And 2359? That’s 11:59 PM. One minute before midnight. The very last minute of the day in military time.
How to Say 2300 Out Loud
The standard way is “twenty three hundred.” You might also hear “twenty three hundred hours.”
With minutes, read them like you normally would. 2330 is “twenty three thirty.” 2305 is “twenty three oh five.”
When Would You Actually See 2300?
2300 is late night, almost midnight. It shows up in situations where people are working odd hours or wrapping up the day.
End of the duty day. Some military operations run until 2300. Watch standing on ships and guard duty rotations often have shift changes at this hour.
Hospital charting. The last scheduled medication round before midnight often falls at 2300. Nurses document vitals and administer meds using military time, so 2300 shows up constantly in patient records.
News deadlines. Newsrooms and media outlets that run on 24 hour cycles often have final deadlines at 2300. Stories need to be filed by “twenty three hundred” for the morning edition.
Store closings. Businesses that stay open until 11 PM list it as 23:00 on internal schedules. Employees clock out at 2300.
Overnight travel. Late night train departures and bus schedules in Europe and Asia use 23:00 for 11 PM departures. These are often the last scheduled runs of the night.
Quick Reference: Times Around 2300

Going the Other Way: 11:00 PM to Military Time
To write 11:00 PM in military time, add 12 to the hour.
11 plus 12 = 23
So 11:00 PM becomes 2300. And 11:30 PM becomes 2330.
Same formula as always. Add 12 to any PM hour and you’re good.
