Teams can start their FIRST LEGO League Challenge season at any point during the official season, running August through April/May. It's recommended that teams target and build their season around Festivals offered in their area. If a team doesn't have a Festival in their area, they can create and run their own Festival open to other teams. Alternately, teams can share what they have learned with family, friends, their school or their community.
Teams can meet as often as the team needs. The majority of non-school based teams meet 6-12 times, for 1.5-2 hrs each meeting.
