D40 (Khavedamsa)
Deity Calculator

The D40 chart, also known as Khavedamsa, is one of the most profound divisional charts (Varga) in Vedic astrology. It is the 40th division of a sign (30° divided into 40 equal parts of 0°45′ each). This chart reveals hidden karmic patterns, ancestral blessings, and the overall auspiciousness & inauspiciousness related to one’s spiritual evolution, past-life deeds, and divine protection.

Each part (Shashtyamsa) in D40 is governed by a specific deity. These deities range from Brahma, Vishnu, Shiva to Yama, Agni, Vayu, Indra, Kubera, Varuna and several other celestial beings. Knowing your D40 deity provides insight into the type of spiritual energy that protects or challenges you, and which deity’s grace you should invoke for overcoming obstacles.

How D40 Deity is Calculated

The D40 divisional chart divides each sign into 40 equal parts (each part = 0.75 degrees). The index of the part (1 to 40) determines the deity. The classical text "Shastamsa" and "Parashara Hora" mention 40 different deities starting from Brahma, Vishnu, Shiva, Ganesha, and others. In our simplified API, we map each part based on the sign and precise degree to return the ruling deity name, Sanskrit transliteration, and the spiritual effect that deity bestows upon the native.

For example, if a planet is placed at 5.5 degrees in Aries (sign number 1), the part index falls in the 8th segment, which corresponds to Yama — the god of Dharma and death, indicating karmic justice, transformation, and strong moral principles.

Significance of D40 in Chart Analysis

The D40 chart is primarily used to assess the overall fortune, misfortune, spiritual merits, and the nature of one’s inner self. It also indicates the type of divine energy that guides the native in critical phases. Many astrologers analyze D40 for:

• Ancestral blessings (Pitru Dosha or Pitru Anugraha)
• Spiritual inclinations and Ishta Devata (personal deity)
• Effectiveness of mantras, yagyas, and remedies
• Understanding the karmic background behind career, marriage & health patterns
• Remedial measures: worshipping the D40 deity helps mitigate afflictions

Using this D40 deity calculator, you can instantly know which deity rules a specific degree/planet in your birth chart or the 40th divisional chart. You can use this for any planet’s position or even for the ascendant lord in D40.

Classical texts like Brihat Parashara Hora Shastra mention that the D40 chart (also called Shashtyamsa) is crucial for judging "good and bad effects" – the blessings of the divine, longevity of relationships, and the ultimate spiritual path. Modern Vedic astrologers rely heavily on D40 for Ishta Devata analysis. Use this tool regularly to check transits or planetary degrees for deeper insights.
