17:00 in 12-Hour Time
17:00 is 5:00 PM.
Written 1700 in military time and said “seventeen hundred hours”. Going the other way, 5:00 PM is 17:00.
The 17:00 hour is the end of the standard working day, and the start of the evening commute.
24-hour clock
17:00
12-hour clock
5:00 PM
Said aloud: “seventeen hundred hours” on the 24-hour clock, “five o'clock in the afternoon” on the 12-hour one.
Why 17:00 converts the way it does
This is the half of the day that actually changes. From 13:00 to 23:00, subtract 12 to get the 12-hour hour and label it PM: 17 − 12 = 5, so 17:xx is 5:xx PM. Going the other way, add 12 to any PM hour except 12 PM itself.
The minutes are the same on both clocks — a whole hour stays a whole hour — and 17:00 is in the afternoon, which is the information the AM/PM label is carrying.
Need this time to actually do something? Set an alarm for 5:00 PM, or use the timer to count a length of time instead of waiting for a clock time.
