जन्मयन्त्र-निर्माण-यन्त्रम् — Janma-Yantra Caster
Choose Bharat substrate (Sūrya-Siddhānta, sovereign · zero foreign-origin numerics) or Drik (refined with neutral numerics). Bharat-mode is the default; the toggle inside the form lets you switch before casting.
Every position rendered here is the output of substrate-derived Sūrya-Siddhānta + Kerala Tantrasaṅgraha (1501) + Bhāskara II lagna mathematics. Nothing is interpreted.

Every longitude on the rendered chart is a finite consequence of (R, g, k) = (ℤ/3³³⁷ℤ, 2, k=337) — a single algebraic triple from which the proposition catalog derives (230 published at DOI v3 · 890 internal, publication pending). See P47 (Sacred-Trinity Scaling Law) for the hardware-grounded derivation.

Free Kundli · Common Questions
जन्म-कुण्डली-प्रश्नाः- How do I read a kundli (Vedic birth chart)?
- A kundli shows the position of nine grahas at your birth moment, computed from Sūrya-Siddhānta mathematics accurate to arc-minutes. Read it by examining your lagna (rising sign), each graha's rāśi and nakṣatra placement, and the Vimśottarī daśā sequence. The chart gives structure — not predictions.
- What is lagna in a kundli?
- Lagna (ascendant) is the zodiac sign rising on the eastern horizon at your exact birth moment and place. It anchors the first house and orients all 12 houses of your chart. An accurate birth time is essential for a correct lagna — even 15 minutes difference can change it.
- What is janma nakshatra in a birth chart?
- Janma nakṣatra is the specific lunar mansion (one of 27, each spanning 13°20′) where the Moon was positioned at birth. It seeds your Vimśottarī daśā sequence and is a key structural coordinate. Our engine computes it from Moon longitude accurate to within ~1 arc-minute of NASA/JPL Horizons.
- What is a dasha period and how is it shown in the kundli?
- Daśā periods are the time cycles of the Vimśottarī system (BPHS Ch. 46), seeded from the Moon's birth nakṣatra. The 120-year cycle divides into nine mahā-daśā periods, each sub-divided into nine antar-daśā sub-periods. The chart output shows your current mahā-daśā and antar-daśā balance.
