Tamil Birth Chart Guide
A Tamil birth chart is a sidereal astrology map. It places the lagna, Moon rasi, nakshatra, and planets at the moment of birth. The chart is often used for family records, personal study, marriage matching, naming, and yearly planning. This calculator gives a structured first view. It does not replace a skilled astrologer.
Why Birth Details Matter
Date and time decide the sky position. Place decides the local horizon. Timezone decides the correct UTC conversion. Even a small time error can change the lagna. A wrong place can shift house cusps. Always check birth records before saving any result. Use the nearest known location when exact coordinates are unavailable.
Main Tamil Chart Parts
Lagna shows the rising sign. Moon rasi shows the mind and daily emotional pattern. Nakshatra gives a finer lunar marker. Pada divides the nakshatra into four parts. Planet houses show where each force acts in life. The lord of a sign is useful for deeper study.
About Ayanamsa
Sidereal systems subtract ayanamsa from tropical positions. Lahiri is widely used. Raman and Krishnamurti are also common in some traditions. Different ayanamsas can move degrees slightly. Near sign borders, this may change a rasi or nakshatra. Review the selected method before comparing two charts.
Reading the Result
Start with lagna, Moon rasi, and nakshatra. Then review planets by house. Notice retrograde labels. They mark apparent backward movement from Earth. Next, study house lords. The example table helps you test common places. CSV export is useful for research. PDF export is helpful for family sharing.
Practical Tips
Keep one spelling for each name when saving records. Record the source of birth time. Note whether the time came from hospital papers, family memory, or an estimated window. When comparing charts, use the same ayanamsa and house option. This prevents false differences. For twins, enter each separate birth time carefully. Minutes can matter for lagna and divisional study during any later reading or archive update work.
Important Note
The formulas are suitable for educational use. Planet positions are approximate. They may differ from professional panchangam software. Use the result as a guide, not as final life advice. For muhurtham, marriage decisions, or formal predictions, consult a qualified practitioner.
