Since 1937, the United States presidential inauguration has included one or more prayers given by members of the clergy. Since 1933 an associated prayer service either public or private attended by the president-elect has often taken place on the morning of the day. At times a major public or broadcast prayer service takes place after the main ceremony most recently on the next day.
