The 23rd September is being repeatedly seeded in a massive amount of movies as a world ending events. This video I noticed only shows a few of these, however there is a huge number of these out there. It's put on number plates, house numbers, receipts, etc. it is shown way too often to  be chance. 

It's is like the seeding for 9/11, they know the date and are throwing it in our faces, as 23rd September. This year 23rd September is the Jewish Yahrzeit which is anniversary of a death in Judaism. I could totally see them doing some real evil on this date. It is also the Fall Autumn Equinox.
