Probably the best place is the Kedington community facebook page this can be found at https://www.facebook.com/groups/456890794432035/ Among the general village chatter it is here you will find the most coverage of events coming up in the village. Don't worry that facebook seems to think Kedington is in Norfolk, Facebook is wrong (We have told them but they continue to insist on being so).
Many of the village's biggest events happen due to the Kedington Community Center. Thier website has all the details including a diary section.
Many events happen at the villages one remaining pub the Barnardiston Arms. They keep the world updated via The Barnadiston Arms Facebook page.
Also Keep an eye on notice boards around the village where many poster appear for village events.
