Galactic Calendar

The Galactic Calendar is a calendar officially used by the System Federation and unofficially used as the standard calendar for the entire galaxy.

In the Galactic Calendar, a Galactic Year is defined as the time that it takes for light to travel 1/100,000 of the diameter of the galaxy. Each year is divided into ten Galactic Months and each month into ten Galactic Days. Dates are written as D.M.Y GY where D is the Galactic Day (1-10), M is the Galactic Month (1-10) and Y is the Galactic Year. For example, the fourth day of the third month of the first Galactic Year would be written as 4.3.0 GY.

The Galactic Calendar was introduced to be a standard calendar for the System Federation as a continuation of the Solar Calendar used by the Human Empire. The first day of the Galactic Calendar (1.1.0 GY) was 1.1.2893 SY, the same date as the official formation of the System Federation. A date in the Galactic Calendar can therefore be easily translated to a date in the Solar Calendar by adding 2893 years.
