Will the system pick up when players turn 13 during the adult league system

Yes, the date of birth is captured during registration and only the age is displayed to club and team admins where relevant. When specific trigger points are met, players can be added to the relevant club teams and added to match sheets. When a player turns 13, if they are looking to play in the adult leagues, the club admin can assign them to adult teams. This makes them visible to team admins who can add them to match sheets. For development badgers and vixens leagues where a small handful of adults play alongside the juniors, the age banding can be set by the competition organiser as there is a minimum age. The player can be moved to these teams once they reach the required age.
