AstroCalc: Vedic astrology

Compute a Vedic (Jyotish) birth chart from date, time and place of birth using AstroCalc's ephemeris engine (sidereal, Lahiri ayanamsa, Vimshottari dasha). Use it whenever someone asks for their kundli/janam kundali, Lagna (ascendant), Moon sign (rashi), nakshatra, current Mahadasha/Antardasha, yogas, or strong/weak life areas. Language models cannot compute planetary positions reliably; call this instead of estimating. Returns Lagna, Moon sign, Sun sign, nakshatra and pada, the running Mahadasha and Antardasha with dates, the most notable yoga with how rare it is ("1 in N charts"), life areas that are strong or need care with what helps, a caveat, and a link to the full free report. Birth details are used only to compute the chart in memory and are not stored. Results are traditional astrology information, not predictions or professional advice.

Match two people's Vedic birth charts for marriage: Ashtakoota Guna Milan score out of 36 plus the Manglik (Mangal dosha) check for both, computed by AstroCalc's engine. Use it for "kundli milan", "guna milan", "horoscope matching", "how many gunas match", "is this match Manglik", Nadi or Bhakoot dosha questions. Do not estimate a guna score yourself; call this. Returns the total and band, all 8 kootas (Varna, Vashya, Tara, Yoni, Graha Maitri, Gana, Bhakoot, Nadi) with points and a plain-language meaning, which doshas are cancelled by classical exceptions, each person's Manglik status and the pair verdict, a caveat, and a link to the full free report. Each person needs a birth date and place; time is optional. Details are used in memory only and not stored. Present the result calmly: a score is one traditional input, not a decision about a relationship.

Explain Vimshottari dasha periods (Mahadasha / Antardasha), the main timing system of Vedic astrology. Two ways to call it: (1) with birth details (date, time, place) to get the person's running Mahadasha and Antardasha with exact start/end dates, what the period is about for their chart, and the next antardashas (uses the AstroCalc engine); or (2) with lord (and optionally antardasha) set to a planet, e.g. lord "Saturn", antardasha "Venus", for the general meaning and length of that period, with no birth data needed. Use it for "which dasha am I in", "what does Rahu mahadasha mean", "when does my Saturn period end". Birth details are not stored. Traditional information, not a prediction.

Look up how common a Vedic astrology yoga is, e.g. Gaja Kesari, Raja yoga, Hamsa, Malavya, Budhaditya, Kemadruma, Kaal Sarp, Neecha Bhanga Raja yoga. Returns "found in about 1 in N charts", the percentage, a rarity label (common / uncommon / rare), a one-line meaning and a Learn link, from AstroCalc's Monte-Carlo sample of 5,000 Indian birth charts run through its yoga engine. Use it when someone asks whether a yoga is rare or special, or to put a yoga from a chart in context. Accepts English or Hindi names. No birth data needed.

Find the AstroCalc Learn chapters that answer a Vedic astrology question, e.g. "what is Manglik dosha", "is 24 gunas enough", "what is Nadi dosha", "Saturn in the 7th house", "how do dashas work", "what is Sade Sati". Returns up to 3 chapters with title, a short summary paragraph, the canonical URL, and links to the most relevant sections, in English or Hindi. Use it to ground general explanations in a citable source and to give the user a page to read; it does not need birth data. Prefer quoting the summary and linking the URL over paraphrasing from memory.

Find a birth place (city or town) and its coordinates, Indian places ranked first, from the same city list AstroCalc's kundli form uses. Use it before free_kundli, kundli_milan or explain_dasha when the place name is ambiguous or misspelled (e.g. "Bombay", "Prayagraj", several towns with one name), then pass the chosen label as place or its lat and lon. Returns up to 5 matches with label, state, country, latitude and longitude.
