Would people arriving on the same date ALL depart on the same date?

[edk35]

For example, all of the people that arrive on the 9th of Jan. will they all depart on the same day. Our daughter said hers was on June 1st and someone else said that the people who arrive on the 9th of Jan. and Feb. 1st both leave on June 1. However someone else posted on here with an arrival date of Jan. 9th on another thread that they depart on May 1st. So does it have to do with "what role you get"?

Thanks

Could be different programs. There are also the Quarter programs, they are shorter, and would depart at a earlier date. It would not be based on role.
