Day of Discovery is a weekly 30-minute television broadcast which offers Bible teaching through a variety of human interest stories, music, and journeys to the lands of the Bible. Day of Discovery's four decades of programming makes it one of the oldest continually running Christian broadcasts in US television history. First airing on May 5, 1968, Day of Discovery began as a television ministry of Radio Bible Class, now known as RBC Ministries, the publisher of Our Daily Bread.

The program airs in the United States and Canada at 7:30 am each Sunday on the ION Television Network. Day of Discovery also appears on satellite television and dozens of other network and independent TV stations.
