EFY Overnight sessions begin Monday morning and conclude early Saturday morning. They are usually held on a college campus. Room and board are included in overnight sessions.

Some overnight sessions are offered as a Special Edition and are held near locations significant to The Church of Jesus Christ of Latter-day Saints. They provide special activities and events unique to their location.

All sessions are led by an adult session director and primarily supervised by young adult counselors who are positive role models for the youth participants.
