The Origin and History of BBY
The Battle of Yavin Reference Point
The Star Wars BBY meaning is centered on the Battle of Yavin, the space battle at the end of Star Wars: Episode IV — A New Hope where Luke Skywalker destroys the first Death Star. This battle is one of the most pivotal moments in Star Wars history—it’s the Rebellion’s first major victory against the Empire and sets the stage for the original trilogy. The Star Wars BBY meaning honors this moment as the defining event of the saga.
Development in the 1990s
The Star Wars BBY meaning was first developed in the early 1990s during the expansion of the Star Wars Expanded Universe (now called Legends). This was when the Star Wars BBY meaning became a standardized system.
1991-1993: The Thrawn Trilogy novels by Timothy Zahn marked time relative to the Battle of Endor (from Return of the Jedi), but didn’t use a standardized system.
1993: The Truce at Bakura by Kathy Tyers was the first book to use the BBY/ABY system, marking its events as 4 ABY.
1996: The BBY/ABY system appeared in official reference material with Star Wars: The Roleplaying Game, Second Edition, Revised and Expanded. The Star Wars BBY meaning became part of official lore.
2000: Star Wars: The Essential Chronology officially used the BBY/ABY timeline in reference material.
2014: The BBY/ABY system made its way into official canon with Star Wars Workbook: 2nd Grade Reading.
2022: The Star Wars BBY meaning finally appeared on screen in the series Andor, with the opening title card “5 BBY.”
Why “Yavin” and Not “Endor” or “Naboo”?
The Star Wars BBY meaning uses the Battle of Yavin because A New Hope was the first Star Wars film released in 1977. Even though it’s “Episode IV” in the saga’s chronology, it was the starting point for audiences. The other calendar system—ASW4/BSW4 (“After Star Wars: Episode IV” and “Before Star Wars: Episode IV”)—was used briefly but didn’t stick around. The Star Wars BBY meaning became the standard because it centered on the most iconic early moment in the saga.

Events before are counted as BBY
