The season will likely begin in September and commence with Championships in July. Clubs will break from league play for periods of rest (including inactivity due to weather), during a winter break (December/January) and/or following the end of the regular season (July).
Regular League runs Sept through Mid Dec, short break until Jan, Futsal period Jan-Feb, League starts back in Feb-June, General idea is to play 34 games.
There are showcases in the later fall (nov-dec) when you play teams form other areas, Futsal Showcase after that, Playoffs or other showcases in June until July.
I have players in both ENCL and DA, ENCL tryout period is May. Existing DA players have to get permission to attend another teams tryout or training and you have to do that during specific dates only.
IF you player is trying out or training with/for another club, follow the protocol otherwise, likely will get back to your home club, I suggest you don't sneak around, seen players dismissed/cut every year for doing so.
ENCL is a good option if you want to play HS which my DD does so she won't be going for girls DA. The only downside is the amount of travel for ENCL and the cost, DA will be more local IMO,
