Imperial Calendar

Calendar established at the creation of the Third Imperium as a universal calendar reform. Dates count from the founding of the Imperium, the year "zero."  Dates before zero are negative, dates after are positive.  For example, Terra discovered jump drive in -2431.  The Imperium was founded in zero.  The Imperial Second Survey was published in 1065.

The year is divided into 365 standard days, which are grouped into 52 weeks of seven days each.  The lengths of days and weeks is a legacy of Terran domination during the Second Imperium.  Days are numbered consecutively, beginning with one.  The first day of the year is a holiday and is not part of any week.  For example, the first day (Holiday) of the year 1116 is 001-1116.  The last day of the year is 365-111.  Weeks of seven days and months of 28 days (four weeks) are used to indicate periods of time, but are not named and are not used to indicate dates.

If only for the purposes of consistency within the Imperium, it would have been necessary for that vast interstellar empire to produce a standard time-keeping system.  Cleon I used the calendar as just one part of a wide-ranging campaign to establish the power of the Imperium throughout its territory.  Within a hundred years, the Imperial calendar was the standard by which history, trade, and bureaucracy were measured.

Imperial timekeeping is based on the time units of the Terran Confederation.  During the Rule of Man, the basic units of the Terran day (24 hours) and the Terran year (365 days) were imposed on First Imperium territories by the Terran conquerors.  During the Long Night, the day and year remained in place in what interstellar trade remained, and by the time the Third Imperium was established, the use of these particular spans for day and year was easily accepted.  The time periods were simplified: the day was made exactly 24 hours, and the year was made exactly 365 days.

The adoption of the standard calendar produced a requirement for names of the days of the week.  The decision was made to scrap the traditional Anglic day names, and instead a series of numbered day names were established.  Over the course of the centuries, these names have settled into galanglic as Wonday, Tuday, Thirday, Fourday, Fiday, Sixday, and Senday.  They are sometimes abbreviated as 1day, 2day, and so on.  Holiday is not part of any week, and the first week of the year begins with Wonday on 002.
