Although the pilot of Gilligan's Island was filmed in Hawaii, the rest of the series was filmed on this set. The set, built in 1964, was located on CBS Studio Center's (old Republic Studios) back lot. The lagoon water is only 4-feet deep.
Remember, the Star Wars universe exists beyond the movies. Many novels, comic books, television series, and spinoff movies expand upon the universe as explained in the 9 canonical movies. Based on the Coruscant tropical year, this calendar uses the Battle of Yavin (when the first Death Star was destroyed) as its epoch or year zero. Thus BBY indicates "Before the Battle of Yavin" and ABY indicates "After the Battle of Yavin".
