--- title: D12 Dwadasamsa Chart description: Draws the D12 Dwadasamsa varga, the chart used for parents and ancestral lineage, from birth date, time, and place. type: tool category: divisional topic: dwadasamsa canonical_url: "https://www.trustastrology.ai/divisional-chart/dwadasamsa-chart" lang: en updated: 2026-08-31 keywords: - d12 - dwadasamsa - varga - lahiri - parents inputs: - name - birth_date - birth_time - birth_place output: on_screen requires_auth: true related: - /divisional-chart - /divisional-chart/lagna-chart - /reports/life-report --- This page is a Vedic D12 (Dwadasamsa) varga calculator from birth date, time, and place. It is not a tropical chart and it is not a prediction of events. ## When to use Use this when you want the D12 Dwadasamsa wheel for parents, ancestral lineage, and past-karma placements. Do not use it as a genealogy certificate, a claim about ancestors as fact, or a substitute for the Life Blueprint PDF report. Classical significance on the result header: Parents, ancestral lineage, and past karma. Classically read as an extension of 12th-house and parental/lineage themes; Pitra Dosha uses D12 as a confirmation chart. Open the D1 Lagna Chart first if you need the natal backdrop (this page is already D1 when the code is D1). ## What you need - Required: Full Name, Date of Birth, Time of Birth (hour, minute, AM/PM), and Place of Birth. Pick a place suggestion from the autocomplete, then India or Outside India. - Optional: a saved family or community kundli via KundliSelector instead of retyping. Don't know time? if the clock time is unknown. - Sign-in: required. PlanetForm wraps PageGateAuthSection. Guests see a gate that says they will sign in and return with details saved. After sign-in, if no astro record exists, the inline astro profile panel collects one before the calculator runs. - Unknown time: Don't know time? offers preset windows (Early Morning around 04:00 through Night around 22:30). House numbers, lagna in this varga, and Dignity that depends on house are then approximate. Finer divisors (D12 uses divisor 12) move more with clock error than D1. - Place: latitude, longitude, and timezone come from the selected place id. A free-typed string that is not chosen from suggestions does not submit. - Submit control: Calculate Dwadasamsa Chart. - Not on the visible form: you do not type coordinates. Gender is not a required visible field on this calculator form. ## What you get On-screen D12 chart and tables. Nothing is exported as a PDF from this URL. A related report product is linked in Related when you want a longer write-up. - Birth Summary: Name, Date, Time, Place. - Chart header: Dwadasamsa (D12), Divisor: 12, and the significance line “Parents, ancestral lineage, and past karma”. - Wheels when returned: South Indian Style, North Indian Style, East Indian Style. Toggling style redraws the same varga, not a second ephemeris. - Planetary Positions table columns: Planet, Sign, Degree, Nakshatra, Nak Lord, Pada, House, Dignity, Relation. The first data row is Ascendant (house 1 in this varga). Planet rows may mark Retrograde (℞) and Combust (☀). - Dignity labels: Exalted, Debilitated, Vargottama, Strong, Weak, Neutral (from the live legend: Exalted — peak strength; Debilitated — weakened; Vargottama — double sign; Strong — positive status; Weak — needs support). - Planetary States card: Retrograde (introspective energy), Combust (too close to Sun), Nak Lord (ruler of the Nakshatra), Relation (house ownership relationship). - Chart Significance card: repeats Dwadasamsa (D12), the significance sentence, and Divisor: 12. - Key Positions: Lagna Sign, Sun Sign, Moon Sign, each with rashi when the engine returns it. - Select Chart: after a result, you can switch to another D-code on the same session without retyping birth details. Bookmark this URL if you want this varga specifically. - Not included: event prediction, medical-legal-financial advice, or a saved file. The on-page report CTA is a separate PDF product, not this calculator’s output. House in the table is the house in **this** varga, counted from this varga’s lagna. Do not paste a D1 house number onto a D12 row. If a cell is blank, omit it; do not invent bindus, sub-lords, or koota points. ## Method Parashari D12 (Dwadasamsa) on the natal moment. Planetary longitudes are sidereal (Swiss Ephemeris with Lahiri ayanamsa). Divisor 12 builds this varga from those longitudes. Wheels and the Planetary Positions table are calculated. The significance sentence and dignity prose are interpretive labels on those calculated points. Each natal sign is split into twelve dwadasamsa. Past-karma wording is a classical varga theme, not a verified family history. The Pitra Dosha calculator may cite D12 as a confirmation layer. This is not KP (no sub-lords or significator levels 1–4). It is not a dasha tree. It is not Ashtakoot matching. Compare with D1 Lagna Chart when you need the complement named in Related. ## How to start 1. Sign in (or complete the guest gate). If KundliSelector appears, pick a stored chart or create a new one. 2. Enter Full Name, Date of Birth, Time of Birth (HH, MM, AM/PM), and Place of Birth (pick a suggestion). A precise time is required for varga houses. Submit with Calculate Dwadasamsa Chart. 3. Confirm Birth Summary, then read the Dwadasamsa (D12) header and Divisor 12, then South/North/East wheels, then Planetary Positions (Ascendant first), then Essential Dignities, Planetary States, Chart Significance, and Key Positions. ## Limits A precise birth time is required. Don't know time? presets keep the form valid but make this varga’s lagna and houses a sketch — more so as divisor 12 gets finer. Dignity and Relation are calculated flags, not a verdict that an event, illness, marriage, or payment will occur. This page does not save a PDF. Reading the table: start at Ascendant (house 1 of this varga), then Sun and Moon in Key Positions, then the remaining grahas. Dignity is computed for this varga’s sign, not copied from D1. Vargottama means the planet’s sign here matches its D1 sign. Relation is house-ownership relationship in this varga, not a statement about people. Wheels: South Indian Style, North Indian Style, and East Indian Style are three drawings of the same calculated varga. If one SVG is missing, the others may still appear. Do not treat a missing style as a missing planet. Sign-in and session: guests cannot complete PlanetForm through the gate. After login, KundliSelector appears when more than one stored chart exists. Choosing a stored chart sends the same name, date, time, and place as the form. A new submit replaces the previous panels; this URL does not email a file. Place and time: pick a suggestion so a place id is sent. Don't know time? keeps the form valid. Quote House, Dignity that depends on house, and this varga’s lagna only when the user gave a clock time they trust. Slow-moving grahas (Saturn, Jupiter, Rahu, Ketu) still shift in fine vargas when the lagna of this division moves. Calculated vs interpreted: longitudes, signs, degrees, nakshatra, pada, house numbers, retrograde, and combust are calculated. Significance text, dignity words, and Relation labels are interpretive overlay. Neither is medical, legal, or financial advice. Neither is a promise that an event will occur. The HTML canonical path is the path in frontmatter `canonical_url`. The markdown twin appends `.md`. Related body links use that public markdown path. Frontmatter `related` uses the HTML path.
