2230 is after noon, so subtract 12 from the hour: 22 minus 12 is 10. Keep the 30 minutes and add PM, which gives 10:30 PM. The same subtraction converts every military time from 1300 to 2359. To go the other way, add 12 to the hour of 10:30 PM: 10 plus 12 is 22, so 10:30 PM is 2230.
How to say 2230
