Riddle Me This: The Synchronized Clock
Let’s all synchronize our watches in this edition of Riddle Me This.
On a 24-hour digital clock that displays hours, minutes, and seconds, how many times in each 24-hour period do all six digits change simultaneously?
Click to Reveal Answer
12 times
ONce per hour – 24 times
twice in each 12-hour period, once when the clock moves from 09:59:59 to 10:00:00 and once when the clock moves from 12:59:59 to 01:00:00. So 4 times each day.
2 – 09:59:59 to 10:00:00 and at 19:59:59 to 20:00:00 – its a 24 hour clock. All other hourly changes, the first digit does not change.
Oops – edit – 3 – also from 23:59:59 to 00:00:00
