Anno Domini Antiterra (A.D.A.) is the calendar of Antiterra. It runs parallel to the terrestrial Anno Domini but is not convertible to it: its year zero has its own origin, and its “Dominus” is not the terrestrial one.

Timeline
- 270 — founding of Alexandria in Antiterra; gesta (campaign-cycle) of Khalim.
- 1784 — the Game of Shadows is installed.
- 1888 — the first zodiacal platforms (Aries, Taurus) are activated by the Regulators.
- 1900 — GRDT founds a domain in Shoa.
- 1901 — the final cycle: Eiffel Tournament, fall of Barbatos, attack on Notre-Dame, approach to the Band of the Dissolution.
- 1946 — the Regulators operate as agents of time after the cycle’s close; a Finisterre prison at the end of the world receives La Jabalina.
- 1955 — the gesta of Caldero closes: nine years between the Finisterre prison and the city of the Río de la Plata, ending with the atoll’s cross of fire, which takes one companion. Sogol is refounded.
- 2055 — the gesta of the children of Sogol.
The Book of Eclipses marks eclipses and platforms at the same interval of a hundred or a hundred and one years. La Jabalina’s gesta also runs on the Crystal calendar (1824–1825 A.E.); both counts are valid and are not translated into each other.
Twelve-year cycles mark periods of liberation and reorganization in A.D.A., a zodiacal mark echoing the Game of Shadows.
Relation to other axes
The A.D.A. axis and that of the Forgotten Realms overlap geographically (the same physical Earth) but not chronologically. Crossings occur through portals or trans-temporal figures: Graz’zt, Paulus (keeper of parallel libraries), GRDT from his Ethiopian base. Paris is a crossing point of times, where the Regulators use chronal travel routinely. The March of the Modrons keeps a clock that does not translate into A.D.A.
The “Ada” rereading
At the close of the End of Antiterra cycle, the rupture of the akashic records (the cell U-571, Sisi turned missing hexagon, Latea devoured) makes reality malleable: “that reality can be a new one — Ada”. After the end of duality, A.D.A. is reread as “Ada”, naming both an era and a nascent entity or faith. The name links to the chain of incarnations Arian → Auro → Idaho → Adam (CDI): “Adam”, the name of the new faith according to the commune, would be the chain’s final incarnation, and Ada “the age named by the entity”.
