This is an add-on for WooCommerce Memberships. By default, WooCommerce Memberships begin as soon as a customer purchases a product that grants them access to the membership. Admins can set durations for memberships but can't specify start and end dates. This add-on allows for the creation of memberships with start and end dates, allowing for things like Empire Tri Club's seasonal membership.
