The Σάββα (Sabbath) is a day of rest and worship observed in various religious traditions, particularly in Judaism and Christianity. In Judaism, it begins at sunset on Friday and lasts until nightfall on Saturday, commemorating God's day of rest after creation. It is a time for family gatherings, prayer, and refraining from work. In Christianity, the Sabbath is often celebrated on Sunday, reflecting the resurrection of Jesus Christ. Many Christians attend church services and engage in rest and reflection. The concept of the Sabbath emphasizes the importance of rest, spiritual renewal, and community.
