Still no count down....
As for the time. AQ always starts at noon Pacific. As for keeping track of the days during break. Here's what I do. Go to the glory store and look at the timer of an item you have purchased that is on cool down. This is the same timer for when AQ will start.
Not sure if the “Coming Soon” is typically only within 1 Hour, or if it normally shows several hours in advance. But the prior week's History has always been removed after only 1 or 2 days after ending (has not been visible all the way up to next series before).
