Yup. Just remember that the +10 is inclusive, this means that you can make 10 days worth of ADRs on that 180 day mark. It's not the 180 day mark, and then 10 days after that (I know, semantics, but it catches a few people off guard).
As for the actual 180day mark... you can plug your dates into
The "PS" Calculator* and it'll spit them out.
* (The PS Calculator is a holdover from the old days of "Priority Seating" vs. Advance Dining Reservations. They're basically the same thing, but it explains why it's called a "PS Calculator"
