1. Contextual or planned days.
Events such as annual homecomings or inviting unchurched persons encourage high attendance from a variety of people.
More inactive and less active church members attend, often to make their annual token appearance.
3. Mother's Day.
Mom desires to have many family members attend church together. The spike thus is typically a mix of nominal Christians and non-Christians.
4. Christmas Eve.
Many unchurched are attracted to the traditions of Christmas, particularly those demonstrated in Christmas Eve services.
