In Vedic science, the moment of physical birth is an imprint of the celestial clockwork. Unlike tropical sun-sign astrology, traditional Jyotiṣa measures the exact sidereal position of the Moon against the fixed stellar backdrop of the 27 Nakṣatras and 12 Rāśis using Chitrapaksha (Lahiri) Ayanāṁśa.
Enter your date, time, and birth location to discover your authentic Moon sign, birth star quarter (Pāda), lunar day (Tithi), and current-year Vedic birthday according to canonical Hindu astronomy (*Jyotiṣa-Śāstra*):
The mathematical principles employed in this calculator are rooted in classical Vedāṅga Jyotiṣa treatises and corroborated by modern positional celestial mechanics:
"तथा द्वादशभिर्मासैः सौरो वर्ष इहोच्यते। प्राक्चक्रभ्रमिणा नित्यं भचक्रस्य ग्रहा गतिः॥"
The foundational astronomical treatise of ancient India, defining the sidereal ecliptic, true planetary longitudes, the precession of the equinoxes, and the 30° division of the twelve solar-lunar signs.
"कृत्तिकाः प्रथमं विशाखे द्वन्द्वं। अहोरात्रे वा एते देवानां यदहोरात्रे... नक्षत्राणि वा एतानि॥"
The earliest canonical catalog of the 27 Nakṣatras, enumerating each celestial mansion along with its presiding cosmic Devatā, sacred symbol, and ritual invocation.
"राशीनां नाम रूपाणि स्वामिनश्च तथा गुणाः। मेषो वृषोऽथ मिथुनः कर्कटः सिंहकन्यके॥"
The monumental compendium of predictive and natal Jyotiṣa, delineating the elemental Tattvas, planetary ownerships, and psycho-spiritual qualities of each Moon sign and Nakṣatra quarter.
Spica (Citrā / α Virginis) pinned at exactly 180° 00' 00" sidereal ecliptic longitude.
Endorsed by the Government of India and the national Positional Astronomy Centre, this standard reconciles ancient observation with modern high-precision ephemerides (VSOP87 and ELP-2000).
Western (Tropical) astrology fixes 0° Aries to the Vernal Equinox regardless of where the stars actually sit in the night sky. Because Earth's axis slowly wobbles (precession of the equinoxes) at ~50.29 arcseconds per year, tropical signs have drifted backwards by approximately 24 degrees over the last 2,000 years.
Vedic (Nirayana) astrology uses true sidereal positions tied to the actual visible constellations. Consequently, your Vedic Candra Rāśi will typically be one sign earlier than a tropical sun sign, reflecting where the physical Moon was actually situated among the stars when you drew your first breath.
