Also don't forget that orientation activities may occur the week prior to the actual start date. My start date was 6/24, but I had to show up 6/17 for the beginning of orientation.
I was so hopeful for a July 1 start date and a few weeks of vacation prior to beginning intern year. My school graduates late--June 1. Seems most residencies I'm interviewing at start orientation by June 9 or 15 🙁
