If you gem ahead it allows you to do the next day early(8 apparently in your case), but you still wait for the normal time for the following day to start... You'll have 24 hours to complete day 9(starting at 12:01 Pacific time 33 hours from now) and 24 hours to complete day 10(starting 24 hours after that).
BTW... What level is your Kingdom and how long did it take you to get all the replies back?
