Yes it is late October now, the first day of lessons is the day after Halloween. Next week or so, Nov 1st.
The 21 Arcana cards become active on 11/11 at 11:11am, meaning anyone with an Arcana card can now sustain their servant for more than a day and use NPs now. The fighting now starts between the 21 Arcana Minors and any other students who want to try with their one-shot. Usually they have been cut down to 7 before this moment, once there are only 7 masters, the time of rest begins until Christmas.
Christmas day is the Debut of the 7 Arcana Majors, at the Winter Ball revealing the masters that will compete in the final leg starting at 00:01 New Years Day. On New Years day, to start the Tournament, the sorting is completed, meaning the Arcana Majors can now use the resources of the house they have chosen to align with.
So was thinking on making it maybe Nov 10th.
