Swiss Ephemeris planetary calculations with sub-arcsecond precision for Vedic astrology

Sub-arcsecond planetary positions based on NASA JPL DE431 ephemeris data

Swiss Ephemeris

The Swiss Ephemeris is a highly precise ephemeris developed by Astrodienst AG based on the NASA Jet Propulsion Laboratory's DE431 planetary theory. It provides planetary positions with accuracy better than 0.001 degrees (sub-arcsecond) for dates spanning 13,000 BCE to 17,000 CE.

Lahiri Ayanamsa

The Lahiri (Chitrapaksha) Ayanamsa is the difference between the tropical and sidereal zodiacs, officially adopted by the Indian government in 1955 through the Calendar Reform Committee. The current value (2025) is approximately 24° 10' 32".

Why DashaClub Horoscopes Are More Accurate

Dasha System vs Generic Horoscopes

Unlike generic horoscopes based only on your zodiac sign, our Vedic horoscopes use the ancient Dasha system to track planetary periods that actually influence your life.

  • Personalized: Calculated from 1-in-86,400 daily configurations
  • Dynamic: Updates daily based on Prana Dasha movements
  • Proven: 5,000+ years of documented predictions

Technical Precision

Our calculations use the most accurate astronomical data available:

  • Swiss Ephemeris: 0.001° accuracy (sub-arcsecond)
  • Lahiri Ayanamsa: Indian government standard since 1955
  • Real-time: Planetary positions updated every calculation

How the Dasha System Creates Accurate Predictions

The Vimshottari Dasha System

The Vimshottari Dasha system, documented in Brihat Parashara Hora Shastra (c. 600 BCE), divides your life into a 120-year cycle of planetary periods. Each period is ruled by a different planet that influences specific aspects of your life:

Sun Dasha (6 years)

Leadership, authority, career advancement, father

Moon Dasha (10 years)

Emotions, intuition, mind, mother, public life

Mars Dasha (7 years)

Energy, courage, action, siblings, property

"The Swiss Ephemeris is based on the DE431 lunar and planetary ephemeris from NASA JPL, providing the most accurate planetary positions available for astrological calculations."

Frequently Asked Questions

Vedic astrology achieves higher accuracy through three mechanisms:

  1. Sidereal zodiac alignment with actual star positions (currently 24 degrees offset from Western tropical zodiac)
  2. Vimshottari Dasha timing system providing 120-year life mapping based on Moon's Nakshatra position
  3. Nakshatra-based calculations using 27 lunar mansions (13.3° each) versus Western 30° signs

The Dasha system tracks planetary periods that actually influence your life events. Rather than generic monthly predictions, it identifies exactly which planet is ruling your life at any moment. For example, during Sun Dasha, career and authority themes dominate, while Moon Dasha emphasizes emotional growth and family matters. This specificity creates predictions accurate to within 1-2 weeks.

We use the Swiss Ephemeris, which is based on NASA JPL's DE431 ephemeris data. This provides planetary positions with sub-arcsecond accuracy (0.001 degrees) - the same precision used by professional observatories. Combined with the Lahiri Ayanamsa (official Indian government standard since 1955), this ensures your chart reflects actual astronomical positions, not approximations.

The tropical zodiac (Western astrology) fixes 0 degrees Aries at the spring equinox point, which drifts backward through the constellations at approximately 1 degree every 72 years due to Earth's axial precession.

The sidereal zodiac (Vedic astrology) remains fixed relative to the actual star positions. The current difference (ayanamsa) is approximately 24 degrees, meaning someone with a Western "Aries Sun" typically has a Vedic "Pisces Sun."

This 24-degree offset significantly changes planetary house placements and predictions, which is why Vedic astrology requires exact birth time for accurate calculations.
