there is NO requirement to answer your phone on your last day off (even under current book).. and now there is no requirement to check your schedule either (current book you have to check between 1800 and 2359) … unless you Volunteer to be an early-check.

0000 on your first day is the earliest you have to answer or be aware of anything on your schedule ; however there are gotchas.., they may have assigned you a 1000 report time for a trip and call you at 0000 to notify you and you might be be able to commute in time.(see above examples) … but it’s your choice to not check your schedule or answer your phone on your last day off.
