How to read 2040
2040 is after noon, so subtract 12 from the hours: 20 − 12 = 8. Keep the minutes (40) and add PM: 8:40 PM. Do not subtract 10: 2040 is not 10:40 PM.
For hours 20 to 23, add 8 to the second digit: 20 gives 0 + 8 = 8, PM.
2040 falls in the evening: 20 hours and 40 minutes after midnight, 86.1% of the way through the day, with 3 hours and 20 minutes left until the next midnight.
How to say it
Pilots and air traffic controllers say each digit: “two zero four zero”. Off the radio, people usually read 2040 as two numbers.
