How to read 2200
2200 is after noon, so subtract 12 from the hours: 22 − 12 = 10. Keep the minutes (00) and add PM: 10:00 PM. Do not subtract 10: 2200 is not 12:00 PM.
For hours 20 to 23, add 8 to the second digit: 22 gives 2 + 8 = 10, PM.
2200 falls in the night: 22 hours after midnight, 91.7% of the way through the day, with 2 hours left until the next midnight.
How to say it
Pilots and air traffic controllers say each digit: “two two zero zero”. Off the radio, people usually read 2200 as two numbers.
