Time

Time was a measurable quantity used to sequence events. Most societies had their own ways of measuring it, mostly through a method of splitting it up into chunks of varying size. For example, a millennium, a century and a decade were all different lengths of time. Often, dates would be used to order different events into a timeline, or to schedule certain upcoming affairs. Dates would usually contain three figures: the day, the month and the year. The positions of the day and the month varied between cultures, though the year usually came last. For example, 12.03.2017 in British English would represent the twelfth of March, 2017. However, 03.12.2017 would be used to represent the same date in American English.

Timekeeping
Throughout the Four Galaxies' history, the standard orbit of the planet Lycil was used as the main timekeeping system. There were roughly 365 rotations every orbit, and about 24 hours in a day, Lycil being extremely similar to Earth. To keep track of time, citizens usually wore portable clocks on their wrists. However, some simply kept them in their pockets if they couldn't afford an attachable bracelet. Most advanced portable clocks, including those from PortaClock and TempoMeter, could be adjusted to represent the time on any given planet within the Four Galaxies. This would be useful for travel or commerce. All dates were represented with Lycil time, and most clocks had two faces: Lycil time and local time.

Eras
Usually, large quantities of time were divided into certain eras. These eras would often represent certain periods of technological, cultural or scientific advancement, though sometimes the eras were divided into political blocks, where a major political change dictated the outcome of that certain time period. A period that encapsulated many eras was often referred to as an eon. For example, the Phanerozoic Eon on Earth contained the Paleozoic, Mesozoic and Cenozoic eras. These eras could be divided further into periods, sub-periods and epochs. For example, the Cenozoic era contained the Neogene period, which in turn contained the Miocene, Pliocene, Pleistocene and Holocene epochs. Earth's eras were split based on geology, and often encapsulated vast quantities of time each. The Four Galaxies' eras were split based mainly on political change, and contained much shorter amounts of time.
