Traditional Jews are very careful about Shabbat. It is a special day. They clean their houses and prepare special food for Shabbat. They dress in their nicest clothes. They sing beautiful songs and say extra prayers in the synagogue. They have dinner and lunch with their families. Many families also invite guests for dinner and for lunch. They eat special delicious food, and sing together traditional Shabbat songs. On Shabbat afternoon people study Judaism together or just visit friends.
