The eleventh hour

I recently went to one of my friends theatre rehearsals.
I drew them practising dancing with fans and tap dancing.
One part of the dance was that they were all in a circle with their fans, and rotated anticlockwise.
The fans lowered and lifted, and to ensure the girls knew where to lower and where to lift, they had to imagine being on a clock face - lower at 6pm and heights at 12.

So there is an 11th hour here, after the height of 12 and begins its transit into the lowest position.
