We restrict the maximum duration of a recurring need to 6 months in order to keep the list of needs listed on Meet The Need current. Allowing needs (especially recurring needs where one need can equate to many occurrences) to be posted more than 6 months out has resulted in needs appearing in search results that are longer relevant. To maintain those recurring needs on an ongoing basis, Key Contacts may continue to add occurrences each week as prior occurrences roll off (because the dates have passed).
