Something that needs to be stated about the movie Crimson Tide: in the film, they DO IN FACT RUN A DRILL, and they run it on October 23rd.
The day in the Movie that they authorize use of live weapons is NOVEMEBER 1st. This is the day where it's "not a drill."
I think it's possible that Q is doing a head-fake on the enemy, and that the ACTUAL booms are coming the day AFTER nukes are authorized in the movie.
That would make "tomorrow" NOVEMEBER 2nd.
Possible I'm overthinking it, but something to consider if you're getting your hoped too high.
