"Time. That's what's left when you strip away everything else. […] From a certain perspective, time's the only thing a thief ever really steals. And it's the only gift an irredeemable disaster can give to anyone."
Chelli Lona Aphra[src]

Time was a measurable part of the structure of the universe, in which the galaxy existed, where events occurred in a sequence. Time was measured with different concepts, such as millennia, centuries, and years. Time could be broken down even further into months, weeks, days, hours, minutes, and seconds, though these divisions were used almost exclusively to refer to the duration of events, rather than the date or time on which they took place. Chronometers were used to track and indicate time through such units of measurement.[1]

Time travel was a mostly hypothetical method of travel through time.[2]

Time keeping[]

"Time, time, there's no time for time."
Inspector Tanivos Exantor Divo[src]

The last great conflict between the Jedi Order and the Sith resulted in a definitive Republic victory. Resetting its capital on Coruscant, history reset its chrono on this date from which the modern Galactic Republic was born. The time before this rebirth was forgotten as a dark age, lumped into a collective whole known as the "Old Republic." As a result of this change, official calendars reset their zero year onto this date.[3] The galaxy used this standardized dating system based off of the galactic capital Coruscant.[4] On Coruscant, a year was made up of twelve months[source?] spanning 365 days of 24 hours each,[5] with no leap years.[6]

During its reign, the Galactic Empire reset the dating system and utilized its own calendar.[7] Sometime after the Battle of Yavin, Ithorian artist Gammit Chond used a calendar system that used the battle as the zero year from which to date galactic history. Dates before the Battle of Yavin were marked "BBY" and dates after the Battle of Yavin were marked "ABY."[8] Galactic Standard Time was a system of timekeeping used by the First Order.[9] Lothal also maintained its own calendar.[5]

Units of Time[]

The most commonly used measurements of time in the Galaxy were the day and the year, both based on the orbital characteristics of Coruscant. The day was based on its rotational period, and the year was based on its orbital period which, due to a convenient coincidence, was exactly 365 times its rotational period. The day was subdivided into 24 hours, each hour into 60 minutes, and each minute into 60 seconds. A period of 7 days was a week. The unit of a month was also occasionally used, but was much less standardized. It was approximately 1/12th of a year. Periods longer than a year used decimal groupings. 10 years was a decade, 10 decades was a century, and 10 centuries was a millennium. Thus, a millennium was exactly 31,536,000,000 seconds long.[source?]

With the exception of the year, these units were primarily used to denote duration rather than chronology, which was usually recorded only to the nearest year.[source?]

Ancient time keeping methods[]

Long before the Galactic Republic, the Domancion Accord was used as the zero year for an ancient dating system.[10]

The C.R.C. was another dating system that set its epoch 7977 years before the Galactic Empire issued an arrest warrant for Princess Leia Organa after discovering she worked with the Alliance to Restore the Republic.[11]

Eras[]

There were several recognized eras in galactic history.[source?]

Name Begins Ends
Old Republic-era/Expansionist Period 25,000 BBY
Middle Era of the Old Republic
Fall of the Old Republic
Republic Era After 1032 BBY 32 BBY
Fall of the Republic 32 BBY 19 BBY
Imperial Era 19 BBY 5 ABY
New Republic Era 5 ABY 34 ABY

Other time periods include the High Republic Era.[12]
