Duty Season

Duty season is the Star Rangers' unit of career time: one UCSD year, taken as the cycle that postings, certification renewals, rank boards and duty rosters all run on. In service speech it is simply a season — a Chief who has "held the section four seasons" has held it four years, an officer promoted "a season before the timeline usually allows" is a year ahead of the ordinary pace, and a superior who sees a specialist "twice a season" sees her twice a year.

The word earns its place the way most Corps vocabulary does, by solving a coordination problem. A service spread across stations, habitats and planets owns no shared weather and no shared local year: a posting can begin in an orbital habitat's manufactured autumn and end in a valley's deep winter forty light-years away, and a career reckoned in local years would not survive its own transfers. The duty season is the standard year worn as working language — the same clock everywhere, whatever the sky outside is doing.

It is a different word from the calendar season a timestamp or a weather report carries, and context separates them without ceremony, the way it separates a ship's watch from a wrist's. Late Summer, 2831 names where the standard calendar stands; four seasons in the posting names how long a Ranger has stood in it. The Corps has never troubled to rename either sense, on the settled institutional principle that a vocabulary problem nobody has ever actually suffered from does not require a solution.
