How to read 2045
2045 is after noon, so subtract 12 from the hours: 20 − 12 = 8. Keep the minutes (45) and add PM: 8:45 PM. Do not subtract 10: 2045 is not 10:45 PM.
For hours 20 to 23, add 8 to the second digit: 20 gives 0 + 8 = 8, PM.
2045 falls in the evening: 20 hours and 45 minutes after midnight, 86.5% of the way through the day, with 3 hours and 15 minutes left until the next midnight.
How to say it
Pilots and air traffic controllers say each digit: “two zero four five”. Off the radio, people usually read 2045 as two numbers.
