The soccer year is broken down into 5 sessions which start and end yearly in September.  Teams train, play league games, an participate in weekend tournaments through each of the sessions.  U6 - U19 teams train individually 1-3 nights per week on outdoor fields in the spring, summer and fall, and in rented local gyms and indoor turf facilities for winter sessions one and two.  

Players at each age level are welcome to join a team at any point within the year provided that there is space available.  If you miss a registration deadline for a particular session you may still be able to train but typically not play games.  There are exceptions if that team has a low player count for that session.
