Is something supposed to happen on the anniversary of Red October? Over on QRV, some people wanted to know why they're saying something is going to happen on November 7th when the anniversary of Red October is October 25th.  The answer is simple. Red October occurred on October 25, 1917 per the old Russian Orthodox Church Calendar, which was also used by the Czar. The Orthodox Church calendar is 13 days behind the Western Calendar. For example, Christmas falls on December 25th in both the Western Christian Churches and all the Eastern Orthodox Churches. However for the Orthodox Churches on the old calendar (not all are), December 25th falls on January 7th.  In other words, when it says January 7 on the Western calendar, it's actually December 25 on the Old Orthodox Calendar. That's why Russians and other Eastern Europeans celebrate Christmas in January. That means if there is going to be an event to coincide with Red October, it will fall on November 7th. https://voat.co/v/QRV/3488676
