On August 1st 2016, at 8:04 A.M., Astronomical Twilight starts again, and the entire process reverses itself, ending at 11:04 P.M. on September 20th, when the Sun (or at least a little piece of it) is once again up all day!

Of course, you already knew this, right?

I am not dealing with you from now on.

The reason that the Sun is absent from view at either pole for 6 months is due to a distinct rotation arising from the orbital behavior of the Earth.

In a fundamentalist regime this great event that happened today is ignored as is the rotational cause behind it.
