The Only API for BOTH Western & Vedic Astrology

Vimshottari Dasha is THE most important thing in Vedic astrology.

It's a 120-year planetary period system that tells you WHEN specific stuff will happen in your life.

Unlike Western astrology which only looks at where planets are right now (transits), Vimshottari assigns every moment of your life to a ruling planet.

The complete system has 10 Mahadashas (major periods): Ketu (7 years), Venus (20 years), Sun (6 years), Moon (10 years), Mars (7 years), Rahu (18 years), Jupiter (16 years), Saturn (19 years), Mercury (17 years).

Within each Mahadasha, there are 9 Antardashas (sub-periods) - like Venus-Mars, Venus-Jupiter, etc.

And within each Antardasha, there are 9 Pratyantardashas (sub-sub-periods) for even more precise day-level timing.

Indian users EXPECT Vimshottari Dasha in horoscope apps - it's how they time marriages, career moves, everything.

Calculating this manually is insane - you need the Moon's exact nakshatra at birth, then do proportional adjustment of the first Mahadasha based on where the Moon sits within that nakshatra.

Our API does this in just <300ms and gives you the complete 120-year timeline with exact start/end dates for all three levels: Mahadasha, Antardasha, and Pratyantardasha.

Plus we track your current period automatically.

Nakshatras are 27 divisions of the zodiac belt (each 13°20' wide) that the Moon passes through during its monthly cycle.

Think of them like super-detailed moon signs - instead of just 12 zodiac signs, you get 27 nakshatras with way more specific personality info.

Each nakshatra has its own ruling deity, symbol, characteristics, and vibe.

Your birth nakshatra (where Moon was when you were born) determines your Vimshottari Dasha starting point AND reveals personality traits even more accurate than sun signs.

For marriage matching (Kundli matching in India), nakshatra compatibility is CRUCIAL - certain combinations are super auspicious, others indicate problems.

Each nakshatra divides into 4 padas (quarters), giving you 108 total divisions.

Our API calculates which nakshatra any planet occupies, including the pada, nakshatra lord (ruling planet), deity, symbol, and characteristics.

For apps targeting Indian users, knowing "rashi and nakshatra" is way more important than knowing sun sign - that's the first thing people ask.

Here's the big difference between Vedic and Western astrology: Vedic uses sidereal zodiac (fixed to actual star positions), Western uses tropical zodiac (fixed to seasons like spring equinox).

Due to Earth's wobble (precession of equinoxes), these two zodiacs have drifted apart - currently about 24° difference.

This gap is called "ayanamsa".

When calculating a Vedic chart, you take the tropical planet position and subtract the ayanamsa to get the sidereal position.

Our API supports 12 different ayanamsa systems: Lahiri (most popular - used by 90% of Indian astrologers), Krishnamurti/KP (precise for KP system users), Raman, Yukteshwar, True Citra, JN Bhasin, Ushashashi, True Revati, True Pushya, SS Citra, Suryasiddhanta, and Fagan-Bradley.

Each system calculates the ayanamsa value slightly differently (±1-2°), and serious astrologers have their preferences.

For developers, this means if you serve BOTH Western and Vedic users, you need to calculate twice - once with ayanamsa (Vedic), once without (Western).

Our API makes this seamless: same birth data, just specify ayanamsa: 'lahiri' for Vedic or ayanamsa: null for Western.

You can even get both systems in one response.

This is HUGE because most APIs force you to choose Western OR Vedic - not both.

Plus, we're the only API offering 12 ayanamsa systems - competitors typically offer 1-3.

Vedic astrology doesn't stop at the birth chart (D1 or Rasi chart).

There are 16 divisional charts (Shodasha Varga) that zoom into specific life areas.

Think of it like this: the birth chart is Google Maps zoomed out showing your whole city, divisional charts zoom in on specific neighborhoods.

D9 (Navamsa) shows marriage and relationships - it's THE chart for predicting spouse characteristics.

D10 (Dasamsa) reveals career and profession path.

D12 (Dwadasamsa) shows parents and ancestors.

D16 (Shodasamsa) indicates vehicles and property.

D24 (Chaturvimsamsa) governs education.

D30 (Trimsamsa) shows misfortunes and challenges.

D60 (Shashtiamsa) reveals past life karma.

Calculating these manually is tedious AF - you divide each zodiac sign into sub-divisions (9 parts for Navamsa, 10 for Dasamsa, etc.) and redistribute all planets accordingly.

Our API calculates all 16 divisional charts in ONE call, returning each chart with planetary positions, aspects, house placements.

Professional astrologers analyze multiple divisional charts together - this is called Varga Chakra analysis.

Essential for apps targeting serious astrologers or offering premium readings.

In India, Kundli matching (Gun Milan) is non-negotiable before marriage - it's how families check astrological compatibility.

The complete Ashtakoot system has 8 Kutas (categories) totaling 36 Gunas: Varna (1 point - spiritual compatibility), Vashya (2 points - mutual attraction), Tara (3 points - birth star compatibility), Yoni (4 points - sexual compatibility), Graha Maitri (5 points - mental compatibility), Gana (6 points - temperament match), Bhakoot (7 points - relationship prosperity), and Nadi (8 points - genetic compatibility).

You need minimum 18/36 points for acceptable match, 24+ is good, 30+ is excellent.

Our API calculates all 36 Gunas AND automatically checks for critical Doshas: Mangal Dosha (Mars in 1st, 2nd, 4th, 7th, 8th, 12th houses from Lagna, Moon, or Venus causes delays/issues), Nadi Dosha (same Nadi = incompatible), and other afflictions.

All this happens in just <300ms.

The API returns detailed breakdown of each Kuta, compatibility percentage, Dosha analysis with severity levels, and suggested remedies.

For matrimony platforms like BharatMatrimony alternatives, this is THE core feature - auto-match thousands of profiles, show compatibility scores with explanations, flag critical Doshas automatically.

Without this API, you'd need to hire Vedic astrology experts to code the complex logic (3-6 months) or buy expensive desktop software ($500-2000).

Our API makes it instant and scalable - process millions of matches.

The Moon moves through all 27 nakshatras in about 27 days (one nakshatra per day roughly).

Each nakshatra has different energy - some are good for starting new things, others for finishing projects, some for relationships, others for spiritual work.

Apps like AstroSage and Co-Star send daily notifications based on current transiting nakshatras.

Using old cached data is useless - the Moon might have moved to a completely different nakshatra with opposite energy.

Our real-time tracking means when Moon enters a new nakshatra, your app knows instantly.

When a significant planet (like Venus or Jupiter) changes nakshatras, that's a big deal for predictions.

Combined with Vimshottari Dasha (which period you're in), you get hyper-personalized daily predictions: "You're in Venus-Jupiter period AND Moon is transiting your birth nakshatra today - excellent for romance and social connections." This level of precision is why apps using our API see 3x higher engagement than apps using weekly generic horoscopes.

Users trust predictions that actually match what's happening in their life.
