Traditionally, the Saturday between Good Friday and Easter Sunday has been called Holy Saturday. It is considered by many to be a day of reflection on the completed work of Jesus at the cross.
The gospels tell us that the day after Jesus died was the Sabbath day. This, of course, was the Jewish day of rest. It also explains why Jesus’ body was removed so quickly from the cross. For the Jew, it was a defilement for a dead body to remain exposed for long periods. This is why Joseph of Arimathea rushed so quickly to retrieve and bury the body of Jesus before the Sabbath began at Sundown. Pilate, being obliged to keep the peace with the Jews, granted the request.
