I’m about to leave on my trip to Italy and just wanted to ask (and/or confirm) a few things to ensure my understanding of this process is correct. I have read some of the other posts related to mine, but just wanted to double check.
 On the Rail Planner app, I tried to look at train times for 9 September (Thursday) at 9 pm, but when the results show up, it gives me 8 September (Wednesday)….?? Why is that? Does this have to do with the time difference between Italy and California (where I currently am)?
 Is it only possible to book reservations via Eurail.com website or the Rail Planner app? Is it possible to book reservations in person at the train stations? (e.g. when I fly into Fiumicino Aeroporto I won’t necessarily know how long immigration and customs will take, so it would be hard to anticipate which train I’ll be able to board). Would train station personnel accept the Eurail Pass on my Rail Planner app?
 Does the TrenItalia app communicate at all with the Rail Planner app? In other words, if I try to book a reservation on the TrenItalia app, will it know I have a Eurail pass?
 Is printing out the reservation ticket absolutely necessary? What if I do not have ready access to a printer whilst traveling?
 On the Rail Planner app, if I click to “My Trip”, it says “Travel days: 4/5 left” even though I set the beginning of my trip to be 6 September. How did I lose a day when I’m not even in Italy yet?
Thanks so much for your help!
