Year

A Year is a unit of time.

• It is a standard Imperial metric.

Description (Specifications)

An Imperial year (a "standard year") is a frequently used large unit of time. It is used to overcome difficulties caused by having non-uniform local times on each world and system.

• It is equal to 365 standard days
• The common Imperial usage is yr.

Construction times for large starships are generally measured in years.

Equivalent Metrics

Other interstellar cultures have different values for a year, generally based on the orbital period of their homeworld around its star.

• Ftahea (Aslan): 320 standard days.
• Pim!bigr (K'kree): 440 standard days.

History & Background (Dossier)

The Solomani define the year as the orbital period of Terra around Sol, the system's primary star. It is equal to 365.25 standard days.

Modern Imperial usage bases the year on the orbital period of Capital round its sun, which happens to have an almost identical orbital period to that of Terra around Sol. Although this metric was common within former Sylean Federation worlds this definition of the year was more broadly adopted following the Solomani Rim War, in order to avoid the use of specifically Terranocentric metrics.

Technologists found the year useful as the concept of the Technology Level and standardized ideas about sophont society development began to take form.
