180+10 11th day question

[Rootskate]

When you book 180+10 when are you able to book the 11th day?

Say you check in on November 13th. I am assuming you can only book the 13th, 14th, 15th, 16th, 17th, 18th, 19th, 20th, 21st, 22nd?

When would I be able to book the 23rd?

180 (13th) + 10 days ( 23rd is the 10mark)

24th would be the 11th
day.
