The Star Wars universe takes place in a fictional galaxy far, far away and does not directly correspond to Earth's timeline. However, there are some references and estimates that can provide an approximate understanding of when the events of Star Wars may have occurred in relation to Earth's history.

Sources suggest that the Star Wars timeline spans thousands of years, beginning with the formation of the Old Republic around 25,000 years before the events of Star Wars: Episode IV A New Hope . The Old Republic eventually gave way to the Galactic Republic, which fought against the Sith Empire . The Sith Empire was destroyed before the founding of the modern Galactic Republic .

The events depicted in the Star Wars films and other media primarily take place during the time of the Galactic Republic, the rise of the Sith, the Clone Wars, the Galactic Empire, and the Rebel Alliance. These events occur over a span of several decades.

While there is no direct correlation to Earth's timeline, it is generally understood that the Star Wars saga takes place "a long time ago" [2]. The exact Earth year is not specified in the Star Wars universe.
