Someone noted on TV yesterday that this coincides with:
Rosh Hashanah 2017 will begin in the evening of
Wednesday, September 20
and ends in the evening of
Friday, September 22
I can’t say that it means anything in particular. Just kinda interesting. Well, at least to me.
Also, reportedly, “International Peace Day” was set for the 11th of September in 2001.
And, in the wake of the islamic terrorist attacks, it was moved to the 21st.
(I have NOT confirmed this part so any comments welcomed)
