    2 times – At 12 midnight and 12 noon, all the three hands overlap.

    Explanation:-
    The hour hand moves 30 degrees in an hour, the minute hand moves 6 degrees in hour and the second hand moves 0.1 degrees.

    Finding the HCF of 30,6 and 0.1 and finding the next times when the hands meet, we get that at only those two times all the three hands gets overlapped.
