CALCULATION FIRST
Methodology
The beta separates astronomical calculation from interpretation and report writing.
Calculation profile
- Sidereal zodiac
- Approximate Lahiri ayanamsha with a numerical boundary review gate
- Whole-sign houses
- Mean lunar node
- Vimshottari Mahadasha, Antardasha and Pratyantar
- India Standard Time; birth dates 1947–2026; website intake is for adults
- Report dates supported through 2030, with a two-year transit horizon
- Vimshottari year: 365.2425 days; explicit birth-time sensitivity checks
Place coverage
The place picker uses the GeoNames India postal-place dataset and displays district and state to distinguish places with the same name. Coordinates are used only for birth-chart calculation. GeoNames source and licence information.
Ephemeris
Solar, lunar and planetary positions are calculated with Astronomy Engine 2.1.19, an MIT-licensed astronomy library. The beta applies its documented sidereal conversion. Swiss Ephemeris/Moshier is used as a separate development reference and is not part of report generation.
How support windows are calculated
The beta scans the next 24 months and divides the timeline at Pratyantar boundaries and Jupiter or Saturn sidereal sign changes. A customer-facing window needs support from at least two dasha levels, a link between obligations and one of savings, work or gains, and a confirming Jupiter or Saturn transit. A stronger label additionally requires both planets to activate the same relevant house and a supportive transit from the natal Moon.
These are ranked planning windows for negotiation, income action, repayment or review. They are not promised debt-free dates. Dates are displayed in India Standard Time and may move if the recorded birth time or selected dasha convention changes.
Interpretation boundary
Report statements are generated from conditionally selected, versioned beta rules with calculated supporting and counter-indicators, using original bilingual templates. No competitor report or external AI service is supplied to generation. They must not invent a customer's actual loan balance, guarantee an outcome, give a fixed debt-free date or replace professional advice.
The reading uses plain black text and small headings. It connects selected money themes, same-sign close conjunctions and Parashari full sign aspects. Node aspects are not used. References identify relevant roles rather than merely list planets. Full evidence is in the appendix. Dignity, combustion and calculated planetary motion qualify the interpretation; positive and limiting factors can coexist. This is not a complete planetary-strength assessment. Prayer selection follows disclosed editorial branches, including a savings-lord/Rahu link within eight degrees. The three short name-prayers have been checked against their traditional name lists. This confirms their text, not a chart-specific ritual prescription or a guarantee of financial change. Specialized remedies, purchases and mandatory fasting are excluded.
Current validation status
The v0.6 calculation profile was compared with Swiss Ephemeris across 1,665 synthetic cases, including 700 samples near sign and lunar boundaries. The largest angular difference was 0.005565 degrees; the largest Moon difference was 0.001596 degrees. Near-boundary disagreements were caught by the review gate, which withholds an automatic report when its classification is uncertain.
A separate Python calculation checked Vimshottari arithmetic. With the same lunar input, timestamps agreed within one millisecond in the tested cases; with independent Swiss lunar input, matching periods' end times differed by up to 20.98 hours. Twenty-six Jupiter and Saturn sign crossings from 2026 through 2032 agreed within 0.81 hours. These are sampled numerical checks, not proof of predictions or a mathematical error bound for every possible birth chart. Interpretation and customer release review remain separate steps.
The v0.6.1 motion extension was independently checked across 1,326 dates, including direct, retrograde and near-station samples. Dignity boundaries, complete versus partial combinations and counter-indicators have separate logic tests. These are checks of implementation, not proof of astrological outcomes.
