On a digital clock how many times in a 24 hour period are consecutive numbers shown? For example 1:23.

Ten times: 12:34, 1:23, 2:34, 3:45, 4:56 each show up 2 times in a 24 hour period. Sep 13 06, 9:51 AM

8 times. 0:12, 1:23, 2:34, 3:45, 4:56, 12:34, 13:45, 14:56 is this right? i included military time Sep 13 06, 9:55 AM

Hmm, Kayla...I wasn't thinking military time myself because a standard digital clock doesn't show military time but that's good thinking! Sep 13 06, 9:59 AM

Most standard digital clocks show "millitary time" in Europe. Sep 13 06, 10:04 AM

I guess either answer is correct then depending on the location. Sep 13 06, 10:16 AM

Yes, it's not even regarded particularly as military time over here. It's what's used in bus and train timetables. I keep all my digital displays on the 24 hour system. By the way, I don't think 14:56 really counts... Sep 13 06, 10:19 AM

No, nor 13:45, although to be fair the question didn't say how many digits had to be consecutive, nor whether they had to make up the complete time. But if we're using the 24-hour clock, what's wrong with 23:45 ? What about allowing wrap-around, and having 9:01 ? Sep 13 06, 10:35 AM

And we can count the other way, and have 3:21 and so on. I'm assuming the questioner means all consecutive numbers, or else you would have 1:12, 1:23, 1:34 and so on to take into consideration. Sep 13 06, 10:41 AM

America has always printed the date sequence (month,day,year) incorrectly as well as "telling time" incorrectly, so hats off to Europe and the rest of the standardized world! Sep 13 06, 11:26 AM

The answer is eleven. You would have 0:12, 1:23, 2:34, 3:45, 4:56, 12:34 and then repeated all of these except 0:12. No military time because in the US digital clocks don't show military time, usually. Sep 13 06, 12:50 PM

May I point out to sandy that the clock is not specified to be American? And to repeat Gnomon's point that in Europe most digital clocks are displaying the on 24 hour system - which we don't call or think of as military time. Sep 13 06, 1:39 PM

I'm sorry, What-A-Mess, but I would not call any of the styles for expressing the calendar date "correct" or "incorrect." They are simply a matter of custom and usage, and we all need to be sensitive to the manner in which other countries and cultures do it.
