Please can someone tell me, how many times during a 12 hour period, do the hands of a clock face opposite each other? I believe its 11. Also, would this be the same, no matter WHAT the starting time? i.e. if the 12 hour period started at 6 o clock, would it still be 11 times? Many thanks for your help.
