Nineteen day feasts
The Nineteen Day Feasts are regular community gatherings, occurring on the first day of each month of the Baha'i calendar. Each gathering consists of a Devotional, Administrative, and Social part. The Nineteen Day Feast serves to increase the unity of the community, and spiritually uplift the community members by having a devotional program, where readings and prayers from the Baha'i holy writings are shared, and a social program where community members can socialize.
