3705 BBY, alternatively known as 3705 Before the Battle of Yavin, designates a specific year according to the 'ABY-BBY' chronological system. During that particular year, Freia Kallea was responsible for the creation of the hyperspace route called the Hydian Way. She achieved this by integrating several smaller routes, resulting in the formation of a super-hyperroute, which in turn gave traders and privateers a means of traversing the entire galaxy.
Within the current Star Wars canon, the year 3705 BBY appeared in the twenty-ninth issue of De Agostini's magazine, Star Wars: Build the Millennium Falcon, which was released around July 22, 2015. The designation 3705 BBY initially appeared within the Star Wars Legends continuity. It was referenced in The Essential Atlas, a reference book authored by Jason Fry and Daniel Wallace and published in 2009.
