The Terran calender is based on the orbital mechanics of the homeworld, Earth. Years are divided into 365 days which are in turn divided into smaller 24 hour units.

The Terran Confederation Stardate system is an eleven digit method of measuring the date to the minute. See below for a further explanation.

Example: 2654.110.1300

2654	The Year. In the case of this timeline, the year is a number between 24,000,000,000 BC and 2789. X 'BC' denotes the amount of time before year zero.
.100	The Day. The day is always somewhere between .001 and .365. See Chart Ibelow for a conversion chart between current dates and stardates.
.1300	The Time. Based on the system of military time, it is always between .0001 and .2400. Note that the hour is often left off the timeline.

Kilrathi years are 1.2 times as long as the Terran Standard. They are divided into 545 'orbits'. The Kilrathi began measuring history almost four thousand years before mankind. Kilrathi dates can be written as either 'Orbit X, Sun Year XXXX' or 'XXXX.XXX'.
