What is Star Time?

Orientation, not urgency

UniTime reframes timekeeping as a positional compass instead of a race against minutes.

Universal operational reference

A shared sidereal baseline lets teams align across regions without redefining local customs.

Transparent assumptions

Every reading exposes its longitude and data source, keeping the model auditable.

Sky-grounded continuity

Link schedules to the same celestial frame no matter which clocks you use on Earth.

Star Date, the yearly position

Star Date describes where we are within the sidereal year cycle counted from 1970-01-01 UTC. It is independent of longitude, so it complements Star Time by adding a calm, universal phase reference.
