So far, I've found the extension is counted in 'calendar' days,
so tomorrow, Tuesday 22, is the deadline.
The next business day after the scheduled filing date, by what I've read, is the 'real' due date, and starts counting 5 calendars days from that very day, so in this case, Friday would be the 'real' vs 'scheduled' due date, making next Tuesday the extension deadline.
So, IMO, I also feel we will have the LONG expected
news today or tomorrow.
