Astrology — Daily Transit Forecast

Engine: Swiss Ephemeris (pyswisseph 2.10.3.2) + Pillow (PIL)

This skill calculates daily transits over a natal chart and generates an astrological forecast for any target date specified by the user (past, present, or future). It renders a composite 2-column chart showing a combined natal+transit wheel and a wide textual forecast panel.

🔬 Precision

All planetary positions are computed using the Swiss Ephemeris library (pyswisseph 2.10.3.2), which is based on NASA's JPL DE431 ephemerides. This ensures planetary position accuracy of approximately 0.003° — the same engine used by professional astrologers and astronomy software worldwide. House cusps are calculated using the Placidus system with exact iterative methods (swe.houses_ex()).

⚠️ Requirements

Requirement	Details
OS	Windows (x64)
Python	3.14.x
Runtime	Microsoft Visual C++ Redistributable 2015–2022 (x64)
Pillow	12.x — `pip install pillow`
Swiss Ephemeris	Bundled as `swisseph.cp314-win_amd64.pyd.dat`

Architecture

daily_transits.py --json  →  JSON data (natal + transits + aspects + houses)  →  draw_daily.py  →  PNG image
         ↕
   daily_transits.py  →  text forecast output

daily_transits.py is the sole calculation engine powered by Swiss Ephemeris. draw_daily.py renders the chart by calling it via subprocess. This guarantees text and graphical output always match.

How Daily Transits Work

Step 1: Natal Chart → Fixed Foundation

The natal chart is the birth snapshot — positions of planets at the moment of birth. This never changes. Computed once from birth date, time, and location.

Step 2: Transit Positions → Moving Planets on Target Date

Transit positions are where the planets are on the user-specified target date (default: today). The user can request a forecast for any date — yesterday, tomorrow, or years in advance.

Step 3: Aspects Between Transits and Natal

When a transit planet forms an angle (aspect) with a natal planet, it activates that natal planet's energy. Aspect lines are drawn directly on the wheel:

Aspect	Symbol	Meaning	Line Style
Conjunction	☌	Fusion of energies — powerful, direct impact	Solid
Opposition	☍	Tension, confrontation, awareness through contrast	Solid
Trine	△	Harmony, flow, luck — energy works naturally	Solid
Square	□	Challenge, friction — crisis that mobilizes	Solid
Sextile	✶	Opportunity — potential that needs action	Solid
Semisextile	⚺	Subtle influence, minor adjustments	Solid
Semisquare	∠	Irritation, minor tension	Solid
Quincunx	⚹	Adjustment needed, discomfort	Solid
Retrograde	℞	Transit planet moving backward	Dashed

Step 4: House Activation (Detailed)

Transit planets falling in specific natal houses show which life areas are activated. Each house is displayed with:

House title and description
Transit planets in the house (with sign, degrees, retrograde status)
Interpretation of each transit planet in the context of that house
Activation context if a natal planet also occupies the same house

House	Life Area
I	Personality, appearance, self
II	Money, values, resources
III	Communication, siblings, learning
IV	Home, family, roots
V	Creativity, children, romance
VI	Health, work, routine
VII	Partnership, marriage
VIII	Transformation, shared resources
IX	Philosophy, travel, higher education
X	Career, reputation, public life
XI	Friends, groups, hopes
XII	Subconscious, solitude, karma

Step 5: AI-Generated Extended Conclusion

An extended forecast summary is generated, including:

Overall energy assessment (powerful/harmonious/challenging/calm)
Transit planet context (sign position, meaning)
Most activated house analysis
Practical recommendations for the day

When run through OpenClaw, the AI agent can provide an enhanced conclusion via the --conclusion flag.

Font Handling

Two bundled fonts in scripts/:

Font	Purpose	Extension
`seguisym.ttf.dat`	Zodiac symbols ♈♉♊... + aspect symbols ☌☍△□...	`.dat` (ClawHub-compatible)
`segoeuisl.ttf.dat`	Cyrillic, latin, digits	`.dat` (ClawHub-compatible)

Both are auto-copied to .ttf at runtime for Pillow compatibility. Per-character font selection ensures zodiac and aspect symbols render correctly alongside Cyrillic/Latin text.

AI Conclusion Workflow (for OpenClaw agents)

Step 1: python scripts/daily_transits.py <date> <time> <city> --json --target-date <date>
Step 2: AI analyzes JSON and writes enhanced conclusion to a file
Step 3: python scripts/draw_daily.py <date> <time> <city> --lang ru --name "Name" --conclusion <file>

When --conclusion is provided, the AI-generated text is used verbatim. Otherwise, the script generates a built-in conclusion.
