"I can hardly believe it…where did the time go?"
"Where time always goes. There's a giant black hole in the center of the galaxy, and it just sucks it right up."
Bria Tharen and Lando Calrissian[src]

Time, a measurable part of the universe's structure in which events occur in sequence, was regulated by Galactic Standard Calendar (which was based around the Galactic standard second) in most places within the galaxy. The invention of hyperdrive allowed spacers to bypass the laws of time physics and keep time dilation from happening during interstellar travel. There were a number of individuals in the history of the galaxy who actually managed to time travel in ways which defied the standard sequence.

Some societies measured time with units other than those used by the Galactic Standard Calendar, such as kets, klekkets, grimnals, cergl-units, and progressions.

Time was ordered around the legendary conflict known as the Battle of Yavin.[1]


In major galactic society, historians have divided galactic history into multiple eras, usually defined by a series of conflicts or a specific ruling . These periods can be named after a particularly notable Chancellor, a war, a government, or for other reasons.

The following is a list of time period widely accepted by galactic society.
