Zelph, I found this :
"Each family should hold a family home evening each week. A family may consist of one person or of a husband and wife. It may include children and other relatives. Whatever the circumstances, each family will be blessed by holding home evenings. The Church keeps Monday evenings free from other activities so families can use this time to hold family home evenings.
The First Presidency said: "We promise you great blessings if you will follow the Lord's counsel and hold regular family home evenings. We pray constantly that parents in the Church will accept their responsibility to teach and exemplify gospel principles to their children. May God bless you to be diligent in this most important responsibility" ("Message from the First Presidency," Family Home Evening Resource Book, iv)."
