Thread: I have a Time Question

24:00 as a time of day isn't technically correct because this would represent the first minute of the 25th hour, and as you know, there are only 24 hours in a day. However, you may sometimes see a reference to 24:00 when discussing durations, as in a specific event that lasts for 24 hours.

Like 24/7 (24 hours a day, 7 days a week)?

I know what you meant. Like I said, that's not technically correct because there is no such time as 24:00, as there are only 24 hours in a day. 24:00 would be 24 hours plus 1 minute.

No, more like a train ride that lasts 24 hours. Wikipedia has some words on this issue on this page: "The notation 24:00 mainly serves to refer to the exact end of a day in a time interval. A typical usage is giving opening hours ending at midnight, e.g. "00:00–24:00", "07:00–24:00". Similarly, some railway timetables show 00:00 as departure time and 24:00 as arrival time. Legal contracts often run from the start date at 00:00 till the end date at 24:00. It should be stressed, however, that "24:00" is a notation for the purposes of clarity and does not represent a distinct clock time."

Actually, I meant you would go from 24:00 to 00:01 but you could also go from 00:00 to 00:01 but that 24:01 would not be correct.
