i am under the impression (and i could be wrong) that they all start July 1st- thats the official start date. however, you have to be there anywhere from 1 to 3 weeks earlier, depending on the program, for orientations, acls/pals, filling out mounds of paperwork, etc. so technically, i guess both beginning of july and beginning of june could be right, depending on what the person is referring to- the actual day you have to be present, or the first day you actually have to "work" and make real decisions about real patients.
