With the numbers falling in consecutive order... how often in a day does a regular 12 hour am and pm clock show only consecutive numbers in the display?
2:34
3:45
4:56 [edit -- missed one!]
12:34
Each twice a day.
10 total.
How many if you count increasing or decreasing consecutive numbers, eg:
1:01
1:23
3:21
etc...
Originally posted by OmnislashI think that's good enough considering "consecutive" probably doesn't include numbers going backwards... so my father is telling me. Another I was thinking of was 10:09 if you consider "09" to be 9.
By my count, the answer is thirty. The times I found are:
1:23
2:10
2:34
3:21
3:45
4:32
4:56
5:43
6:54
9:10
10:11
11:10
11:12
12:11
12:13
Fifteen times, every twelve hour period.
Is this correct?
I find it funny that almost any riddle on this forum can be questioned.

some digital clocks (watches, certainly--mine does) can include seconds so you can also have 01:23:45 and 1:23:45, as well as 12:34:56.
in my lifetime, there have been two occasions of what i call "great progression".
one was 01:23:45 6/7/89 and the other was 12:34:56 7/8/90, thoguh the latter is not a "true" progression since zero is less than one. since hours cannot go above twelve (or 23) and the others 59, i don't believe you can find any more like this.
anyone else thank of any others?
