Time, oriented south.

AQStrato is a Southern Hemisphere astronomical civil calendar. The year opens with Renewal on 23 September, follows twelve English-named months, preserves Gregorian interoperability, and adds a deep-time Solar Year and planetary sky designation.

A complete civil calendar

Not a horoscope. A usable calendar.

AQStrato separates astronomy from interpretation. Calendar dates, seasons, equinox records and Jupiter–Saturn sky stations are computational labels. They make no claims about personality, fate or spirituality.

01

Southern spring New Year

The AQStrato civil year begins on 23 September. 22 September is the final day of Tillage; 23 September is 1 Renewal.

02

Deep-time Solar Year

Year numbering uses the nominal Chibanian geological boundary as its epoch convention, with the present Meghalayan age shown as a nested scientific context.

03

Gregorian interoperability

Every AQStrato day maps to an ordinary Gregorian date, so events, invitations, public holidays and device calendars remain interoperable.

Scientific structure

The sky is recorded, not interpreted.

AQStrato records the actual September equinox separately from the civil New Year boundary. A Jupiter–Saturn designation records the two planets' 30° ecliptic sectors at the equinox, producing labels such as Epsilon–Alpha. This is positional astronomy, not astrology.

EQUINOX

Seasonal anchor

The Southern Hemisphere's September equinox provides the astronomical context for Renewal.

JUPITER

12-sector station

Jupiter supplies the faster astronomical station in the year designation.

SATURN

Slow station

Saturn supplies a slower second station, creating a repeatable sky-state label.
