As a result of these principles and intents, ADF groves are required to have open-to-the-public rituals on or near the eight "High Days" of the common Neopagan calendar such as Bealtaine, Lughnasadh, and Samhain (the holidays of the Wheel of the Year). Such rituals follow an established "core order of ritual" and are expected to focus on one particular pantheon or "hearth culture" for that high day. ADF groves are also required to perform some kind of public service on a quarterly basis (cleaning up parks and other ecological activities are popular).
