`space::time::CivilDate`

cheatah-space v0.1.0-alpha — Biome Standard 0.6.5-alpha

A calendar date in the proleptic Gregorian calendar, astronomical year numbering.

A plain aggregate: no invariant is enforced on construction, so a CivilDate can hold 2026-02-30. Ask is_valid_civil() when the value came from outside; the conversions here are total functions over whatever they are handed.
