Great idea Bruce!

This graph was for both hemispheres, N & S.:

When I get back from work in 12 hours, I will do exactly as you
suggest.

Meanwhile, here are two daily histograms to consider:

Northern Hemisphere only - all years combined:

and Southern Hemisphere only - all years combined:

It looks for now like there is a small July peak in the Southern
Hemisphere as well, in their dead of winter, but data is
obviously spottier.
