How to read 1700
1700 is after noon, so subtract 12 from the hours: 17 − 12 = 5. Keep the minutes (00) and add PM: 5:00 PM.
For hours 13 to 19, ignore the 1 and take 2 from the second digit: 17 gives 7 − 2 = 5, PM.
1700 falls in the evening: 17 hours after midnight, 70.8% of the way through the day, with 7 hours left until the next midnight.
How to say it
Pilots and air traffic controllers say each digit: “one seven zero zero”. Off the radio, people usually read 1700 as two numbers.
