Formal Establishment of a Horizon Calendar

Era beginning/end

Seeking to preempt issues of dates not matching from planet to planet, the New Terran Republic creates the Horizon Galactic Calendar, centring all galactic events on the planet Horizon's 26-hour, 365-day cycle. The Calendar was intended as a top-level calendar, allowing other planets to develop their own calendar systems, while still serving as a centralized means of date keeping.
