Aapka chart kaise
calculate hota hai.

Aasmaan kaise padha jaata hai

Planet positions poori planetary theory se bani compact VSOP87B tables se nikalti hain. Website ki tables ko poori tables se milana independent astronomical references ki jaanch se alag hai. Moon aur Pluto ki apni calculation methods hain.

Poori pipeline: birth date + time + city → UTC → Julian Day → VSOP87 planetary longitudes → apparent geocentric ecliptic longitudes (nutation, aberration aur precession samet) → sign aur degree. Moon ki apni dedicated high-precision theory hai. Pluto Meeus ka astrometric solution use karta hai.

Houses Placidus system mein compute hote hain — Western astrology ka sabse zyada use hone wala system. Ascendant aur Midheaven birth location ke Local Apparent Sidereal Time se nikalte hain.

Kitna accurate hai?

Hamara published benchmark das charts ko alag se liye gaye NASA/JPL data se milata hai. 100 planet comparisons mein sabse bada antar 0.03° se kam (lagbhag 1.3 arcminute) tha. Yeh ek sample hai, 1900–2100 ki har date ki guarantee nahin.

Birth time zaroori hai. Rising-sign ki duration latitude aur sign ke saath badalti hai; do ghante sirf ek rough average hai. Time na ho to local noon par planet positions estimate karte hain, Moon-sign uncertainty check karte hain aur Rising, Midheaven aur houses chhupate hain.

Benchmark dobara kaise chalayein

Production engine ko NASA/JPL Horizons ki saved observer-table values se milate hain: Earth centre, date ki apparent ecliptic longitude, quantity 31, airless aur Universal Time. Original headers, rows, precision aur request URLs reference ke saath rakhe hain. Normal builds aur tests kisi reference service ko call nahin karte. Poori aur shipped VSOP87 tables ki alag tulna sirf trimming ka asar maapti hai.

Aapka data aapke paas rehta hai

Har calculation poori tarah aapke browser mein chalti hai. Aapki birth date, time aur city kabhi aapke device se bahar nahin jaate — koi server aapka birth data receive nahin karta, koi account nahin hai, aur aapki birth details se aapko kabhi track nahin kiya jaata.

Chart sharing birth data ko seedha link ke andar hi pack karke kaam karti hai. Shared link hi chart hai — na database, na stored records. Link jiske paas hai, sirf wahi data dekh sakta hai, aur bas tab tak jab tak URL uske paas hai.
