Each year, Jehovah’s Witnesses hold a “Special Assembly Day” and a two-day “Circuit Assembly”, held in each circuit worldwide. Each circuit comprises several congregations in a geographical area. These are held either in Assembly Halls owned by Jehovah’s Witnesses, or in rented facilities, such as public auditoriums. Once a year, Jehovah’s Witnesses come together at larger assemblies called “District Conventions” which are usually three days long. These conventions consist primarily of Bible-based sermons, including demonstrations and experiences of their preaching work. They also often feature live, full-costume dramatic plays re-enacting biblical accounts, such as Moses and the Plagues of Egypt, and Lot in Sodom and Gomorrah.
