Star Wars Timeline: Chronology Across 6 Galactic Eras

Chronology Summary: The canonical star wars timeline measures galactic history around the defining Battle of Yavin, dividing events into BBY (Before the Battle of Yavin) and ABY (After the Battle of Yavin). Official storytelling spans six major narrative eras from the High Republic down to the First Order.

Historical reckoning grounds myth. In science fiction worldbuilding, tracing the rise and collapse of interstellar civilizations requires an objective temporal calendar. The galactic chronology crafted across decades of novels, animated series, and feature films forms a coherent narrative architecture spanning thousands of standard years.

How Does the Galactic Calendar Anchor the Star Wars Timeline?

The galactic calendar anchors the star wars timeline using the Battle of Yavin as its foundational zero-point, dividing all galactic history into BBY (Before the Battle of Yavin) and ABY (After the Battle of Yavin). This coordinate system provides an objective framework for organizing millennia of galactic political shifts.

Zero defines perspective. Just as our terrestrial Gregorian calendar reckons time backward and forward from a single central date, galactic historians adopted the destruction of the first Death Star as the definitive turning point of modern history. Prior to this victory, the galaxy operated under various localized reckoning systems, including the Coruscant Reckoning (C.R.) and the Ruusan Reformation calendar.

When selecting your preferred viewing sequences for the episodic films, understanding BBY and ABY metrics clarifies character ages, technological developments, and planetary alliances across three generational conflicts:

• The Coruscant Solar Standard: In-universe time is measured according to the orbital cycles of Coruscant, the galactic capital. A Coruscant Standard Year comprises exactly 368 standard days, each containing 24 standard hours.
• The Negative Progression (BBY): Dates prior to the Battle of Yavin count downward toward zero. An event occurring in 32 BBY takes place thirteen years before an event occurring in 19 BBY.
• The Positive Progression (ABY): Dates following the Battle of Yavin count upward indefinitely. The destruction of the second Death Star at Endor occurs in 4 ABY, while the assault on Starkiller Base takes place in 34 ABY.

Archival records within our galactic history archive adhere strictly to standardized BBY and ABY dating conventions established by the Lucasfilm Story Group.

Which Six Storytelling Eras Define Modern Galactic History?

Six official storytelling eras define modern galactic history: The High Republic, Fall of the Jedi, Reign of the Empire, Age of Rebellion, The New Republic, and Rise of the First Order. Lucasfilm officially unified these designations to classify all canonical media across clear chronological chapters.

Eras categorize civilizations. Rather than viewing the galaxy through isolated character adventures, analyzing historical epochs illuminates systemic cultural transformations:

1. The High Republic (circa 500 to 100 BBY): The golden age of the Galactic Republic and the Jedi Order, characterized by territorial expansion into the Outer Rim, gleaming white-and-gold visual architecture, and philosophical harmony.
2. Fall of the Jedi (100 to 19 BBY): An era of institutional decay and creeping political corruption, culminating in the Trade Federation blockade of Naboo, the devastating Clone Wars, and the catastrophic execution of Order 66.
3. Reign of the Empire (19 BBY to 0 BBY): The dark two-decade autocracy under Emperor Palpatine, witnessing the rapid militarization of star systems, the subjugation of alien populations, and the underground birth of organized insurgencies.
4. Age of Rebellion (0 BBY to 5 ABY): Open military conflict between the Rebel Alliance and the Galactic Empire, spanning the destruction of both Death Stars and terminating at the Battle of Jakku.
5. The New Republic (5 ABY to 34 ABY): The fragile three-decade restoration of democratic rule, decentralized planetary disarmament, and the rise of warlord remnants in the unexplored Outer Rim.
6. Rise of the First Order (34 to 35 ABY): The swift blitzkrieg assault by Imperial successor fanatics armed with planet-killing technology, ending with the galaxy-wide uprising at the Battle of Exegol.

What Major Turning Points Occur in Each Historical Period?

Major turning points occur across each historical period, fundamentally realigning galactic power balances through military revolutions, constitutional collapses, and force awakenings. Each milestone marks the transition from one governing philosophy to the next.

Documented milestones reveal pattern. In official reference materials published in Star Wars: Timelines, historians document verified dates for decisive continental and space engagements:

Patterns repeat across centuries. The transitions from peace to militarization consistently involve orchestrated crises that convince democratic legislative bodies to surrender emergency executive authority to ambitious dictators.

How Does the 2014 Canon Reset Distinguish Legends from Canon?

The 2014 canon reset distinguishes official Canon from Legends by establishing an absolute editorial dividing line on April 25, 2014. Prior Expanded Universe materials were rebranded as Legends, while theatrical films, the 2008 animated series, and subsequent releases formed a singular unified continuity.

Clarity eliminates contradiction. Across thirty-five years of Expanded Universe publishing, hundreds of authors produced novels, comics, and video games with varying degrees of internal consistency. When Lucasfilm initiated production on sequel films, the Lucasfilm Story Group reorganized the entire corpus:

• Official Canon: The six episodic feature films (Episodes I through VI), the 2008 The Clone Wars film and television series, and every novel, comic, game, and television project published after April 2014. All modern releases undergo unified editorial review to prevent factual discrepancies.
• Legends (Expanded Universe): All novels, graphic novels, roleplaying sourcebooks, and video games published prior to April 25, 2014. While non-canonical to ongoing screen productions, Legends acts as a creative reference reservoir from which creators frequently reintroduce beloved characters, such as Grand Admiral Thrawn.

Galactic History Myths vs Documented Lore

Frequently Asked Questions About the Star Wars Timeline

What does BBY and ABY stand for in the timeline?

BBY stands for Before the Battle of Yavin, and ABY stands for After the Battle of Yavin. This dating system establishes the climactic space battle from the 1977 original film as year zero for organizing all galactic historical events.

How many years elapsed between Episode III and Episode IV?

Exactly nineteen standard years elapsed between Revenge of the Sith (19 BBY) and A New Hope (0 BBY). During this nineteen-year span, the Galactic Empire consolidated power, hunted surviving Jedi, and completed construction on the first Death Star.

How long did the Clone Wars last?

The Clone Wars lasted exactly three standard years, beginning with the Battle of Geonosis in 22 BBY and terminating with the death of the Separatist Council on Mustafar and the execution of Order 66 in 19 BBY.

Is the Knights of the Old Republic game official canon?

The original 2003 video game is classified as Legends. However, specific characters and planets from the Old Republic era, including Darth Revan and the planet Moraband, have been officially reintroduced into modern canon through animated series and visual dictionaries.

What is the earliest known era in canonical galactic history?

The earliest canonical era currently designated by Lucasfilm is the Dawn of the Jedi, set approximately 25,000 years before the Battle of Yavin. This ancient epoch explores the origins of the Jedi Order and the first sentient beings who learned to wield the Force.
