I've purchased an Ultimate ticket on the Disney Website and I entered the day of arrival: 7th September (5 days to go! 

)
I received a Will Call ticket that I'll exchange at the park or at the hotel (and I cannot link it to MDE so no FP+ reservations yet
). On the Will Call ticket there is written the arrival day.
My question for the knowledgeable Disers is: do the 14 days of my ticket start the 7th or after I use the ticket for the first time, like the MYW tickets?
I'll stay 14 nights/15 days and I have to choose if using the ticket the first or the last day, but if I have not an option I would plan around the 7th being the first day.
Thanks
