Vedic astrology, also known as Jyotish Shastra, is an ancient Indian system of astrology rooted in the Vedas — the oldest sacred texts of Hinduism. Unlike Western astrology, which uses a tropical zodiac, Vedic astrology uses the sidereal zodiac, aligning planetary positions with constellations. The Vedic Astrology Calculator is a powerful tool that generates your detailed birth chart (Janma Kundali) and provides deep insights into your life path, career, relationships, and spirituality.

Using this tool is simple. All you need are three pieces of information:
🔢 Input Fields:
- Date of Birth – In day/month/year format.
- Time of Birth – Accurate to the minute if possible.
- Place of Birth – City and country for latitude and longitude calculations.
📤 Output:

📐 How the Calculator Works (Plain Text Formulas)
The core calculations involve astronomy, time zones, and planetary ephemerides. Here's how it works at a high level:
1. Sidereal Time Calculation
Sidereal time is used to determine the position of the constellations at the moment of your birth. It depends on:
Sidereal Time = Local Mean Time + (Longitude/15) + Correction factors
2. Ascendant (Lagna) Calculation
The Ascendant is the zodiac sign rising on the eastern horizon at birth time.
Lagna = Sign that intersects the eastern horizon based on latitude, longitude, and sidereal time
3. Planetary Positions
Each planet’s degree is calculated using ephemeris data and adjusted for the Ayanamsa (a fixed correction factor for precession).
Vedic Planet Position = Tropical Position − Ayanamsa (typically Lahiri value)
4. Moon Nakshatra
There are 27 Nakshatras, and the Moon's position determines your emotional nature.
Nakshatra = Degree of Moon ÷ 13.333 (each Nakshatra spans 13°20')
5. Dasha Calculation
The Vimshottari Dasha system assigns periods ruled by different planets based on your Moon's Nakshatra.
Mahadasha starts with the ruler of the Moon's Nakshatra at birth
🧮 Example Vedic Chart Result
