Indian Ephemeris of Planets Positions: According To The Nirayana or Sidereal System For 1997 A. D. (1997 Edition)

The Indian Ephemeris of Planets Positions: According to the Nirayana or Sidereal System for 1997 A.D. (1997 Edition) is a significant astronomical and astrological publication that provides the positions of celestial bodies—such as the Sun, Moon, planets, and other astronomical points—based on the Nirayana or Sidereal System. This system is widely used in traditional Indian astrology (Vedic astrology).

Key Points About the Ephemeris:

1. Sidereal (Nirayana) vs. Tropical System:

   • The Sidereal System (Nirayana) is based on the fixed stars, and it considers the position of planets relative to the constellations or stars. It contrasts with the Tropical System, which is used in Western astrology and is based on the position of the Sun relative to the Earth's equinoxes.

   • In the Nirayana system, the position of planets is calculated using the precession of the equinoxes (the slow shift in the position of the Earth’s axis), and the positions are aligned with the fixed stars.

2. Importance in Indian Astrology:

   • This ephemeris is essential for those practicing Vedic astrology, also called Jyotisha, as it provides the precise positions of celestial bodies at any given time, necessary for casting accurate horoscopes.

   • The positions provided are used to predict events, analyze personal charts, and understand the influence of the planets and their transits.

3. Contents:

   • Planetary Positions: The book includes detailed information on the positions of planets like Mars, Venus, Jupiter, Saturn, and the nodes (Rahu and Ketu), along with the Sun and Moon, for each day of the year.

   • Lunar Nodes (Rahu and Ketu): In Indian astrology, the positions of the lunar nodes, Rahu and Ketu, are considered very significant in determining events and karmic influences.

   • Nakshatras: The positions of the planets are also given in terms of the Nakshatras (lunar constellations), which are 27 segments of the sky that the Moon passes through during its monthly journey.

   • Other Astronomical Data: This ephemeris may also include additional data like the Ayanamsa (the longitudinal difference between the Sidereal and Tropical zodiacs) and planetary retrogradation.

4. Usage:

   • Astrologers: Practicing astrologers use the ephemeris to cast horoscopes, calculate planetary transits, and make predictions.

   • Astronomical Researchers: Those studying Indian astronomy and related sciences may use the ephemeris to understand the traditional methods of calculating celestial positions.

   • Religious and Cultural Observances: The ephemeris is used for setting the dates of various Hindu festivals and religious observances, which are often based on lunar phases and planetary positions.

5. Format of the Ephemeris:

   • Typically, the ephemeris for each year is laid out in tables, with columns representing the day of the year and the corresponding positions of the planets in the Sidereal Zodiac, often using the Lahiri Ayanamsa (a popular calculation for the precession of the equinoxes).

   • The zodiac signs used in the Nirayana system are the same as those used in Vedic astrology (Aries, Taurus, Gemini, etc.), but their positions are adjusted according to the sidereal rather than the tropical system.

1997 Edition Specifics:

The 1997 Edition of the Indian Ephemeris would have provided the planetary positions for the year 1997, including details for each day or specific periods (like monthly or weekly intervals). This would have been useful to those practicing astrology at the time, particularly for analyzing planetary transits and their effects on various zodiac signs.
