Chart, timing, report, relationship, transit, and election services available to Astrotechne workflows.
Astrotechne Engine
Built from scratch for serious astrology
Astrotechne runs its own calculation engine so chart math, timing techniques, report evidence, and source-aware rules can be handled consistently.
The engine is not a wrapper around a generic astrology API. It is Astrotechne's own calculation layer, built so natal charts, timing techniques, election searches, relationship analysis, transit analysis, and report evidence all draw from the same rules and astronomical positions.
CALCEPH is the astronomy library Astrotechne uses to read high-precision planetary ephemerides: tables that describe where planets, asteroids, and other bodies are at a given time. Those ephemerides are based on the same class of astronomical data used by NASA and JPL.
NASA is the United States space agency. JPL, the Jet Propulsion Laboratory, is a NASA-managed research center known for spacecraft navigation, planetary science, and solar-system data. Astrotechne uses that astronomical foundation, then adds the astrology-specific layer: techniques, source citations, doctrine categories, and report-ready interpretation structure.

Timing techniques
15
Traditional timing families Astrotechne can compare in forecast and timing work.
Doctrine and reference libraries
Astrotechne keeps interpretation rules close to their source material, so calculations can point back to reviewed citations and stable doctrine categories.
Source organization
1 doctrine group
Public source-bundle taxonomy for doctrine groups represented by the engine.
Interpretive organization
9 rule categories
tradition, topic, rule type, review status, chart contexts, source tags, rule triggers, source citations, automation readiness
Reference library
Citation registry
Reviewed citation records that connect interpretive claims back to their sources.
Reference library
Rule registry
Astrological rule records used to keep interpretive logic organized and auditable.
Reference library
Vocabulary registry
Shared vocabulary for traditions, topics, techniques, and interpretive categories.
Reference library
Source bundle
A bundled reference set of formulas, citations, doctrine groups, and source metadata.
15 timing techniques
These are the traditional timing families currently represented in the engine for forecast and lifetime-timing work.
Timing technique
Annual profections
A yearly house-and-planet emphasis used to frame the main topic of a year.
Timing technique
Annual return divisions
Yearly return charts divided into smaller periods for month-by-month emphasis.
Timing technique
Circumambulations
A traditional timing method that follows a chart point through directed periods.
Timing technique
Climacteric years
Age-based milestone years treated as stronger turning points in some traditions.
Timing technique
Decennials
Ten-year rulership periods used to describe longer chapters of life and emphasis.
Timing technique
Firdaria
Planetary periods from medieval astrology, organized as major and minor rulers.
Timing technique
Length-of-life techniques
Historical longevity calculations preserved as source-backed research material.
Timing technique
Lord of the orb
A traditional way of assigning period emphasis through planetary rulership.
Timing technique
Novenaria
Nine-part timing periods used to break a life or year into smaller chapters.
Timing technique
Phasis
Visibility events that mark when a planet emerges, disappears, or changes emphasis.
Timing technique
Planetary hours
Day and night divisions assigned to planetary rulers for short-range timing.
Timing technique
Primary directions
A symbolic timing method based on the motion of the heavens after birth.
Timing technique
Planetary returns
Moments when a planet returns to its natal position, such as solar returns.
Timing technique
Planet visibility
Astronomical visibility conditions used to judge whether a planet can be seen.
Timing technique
