2017 (Earth-Prime)

The **timeline** of Earth-Prime is a series of significant events listed in chronological order. The timeline is always in a constant flux when a person with access to some form of time travel goes backwards in time and changes events, creating a new timeline from that moment onward, though some events like the big bang are always supposed to happen.

Because of the nature of Earth-Prime, many events from its constituent Earths have also taken place but with slight changes to certain events. See Timeline of Earth-1, Timeline of Earth-3, Timeline of Earth-38, Timeline of Earth-42, Timeline of Earth-616, Timeline of Earth-666, Timeline of Earth-TUD5 to see more events.

This is a timeline of events that occurred during **2017**.

The following events that takes place in these years; **2017**, also known as **-2683 LY** (according to the Lothal Calendar), **5941 BFE** in the Imperial calendar, **151,065 AJC** in the Jedi Galactic calendar, and the years: **2017 AD** (Anno Domini) in the C.R.C. calender, with the latter also being known as the original calendar, later known as **5960 BBY**.
