Ya I think it was June 1st, but the application opened up in May and you were able to send in your transcripts then, which is a good idea because it takes them forever to mark them received.I believe that this year AACOMAS began accepting applications on June 1st.
Someone please correct me if I am wrong.
Some people got accepted as early as august/early september this cycle. Imagine knowing almost a year in advance! This blew my mind. I was still checking my computer every day waiting to get verified at that point!
