What is the Chaturthamsa chart (D4) in Vedic astrology?

The Chaturthamsa (D4) is a divisional chart in Vedic astrology that divides each of the 12 Rasi signs into four equal segments of 7 degrees 30 minutes each. These four segments map to four different signs, creating a specialized chart that shows the deeper karma around home, property, vehicles, mother, and inner happiness — themes governed by the 4th house in the main birth chart.

What themes does the D4 chart analyze?

The Chaturthamsa (D4) chart specifically analyzes: (1) Home and domestic life — the quality and emotional tone of your living environment; (2) Property and real estate — the karma of acquiring, maintaining, and enjoying property; (3) Vehicles — in traditional texts, the 4th house governs conveyances; (4) Relationship with mother; (5) Inner happiness and contentment — the D4 goes deeper than the Rasi chart in showing what genuinely nourishes your sense of security.

How accurate does my birth time need to be for the D4 chart?

Very accurate. Each D4 segment spans only 7 degrees 30 minutes — a difference of 30 minutes in birth time can shift a slow-moving planet like Saturn by 1–2 degrees, which may move it to a completely different D4 segment and sign. For divisional charts D4 and above, birth time accuracy within 10–15 minutes is recommended for reliable results.

Which planet is most important in the D4 chart?

The Moon is the primary significator for inner happiness and relationship with the mother in the D4. Jupiter is the most auspicious planet for property and domestic blessings. Saturn governs property acquired through persistent effort. Mars governs real estate, construction, and conflict in domestic settings. The 4th house lord of the D4 chart itself (which may differ from the Rasi chart) is also critical.

How is the D4 chart calculated?

For each planet, divide its degree position within its Rasi sign by 7.5 (= 30/4) to find which of the four segments it occupies (0–3). The D4 sign is then determined by: (signIndex × 4 + segment) modulo 12. For example, a planet at 22° Scorpio: Scorpio is sign 8 (0-indexed: 7), degree in sign = 22°, segment = floor(22/7.5) = 2, D4 sign = (7×4+2) % 12 = 30 % 12 = 6 = Libra.

What does it mean to have many planets in one D4 sign?

A concentration of planets in one D4 sign intensifies that sign's energy in your home, property, and happiness karma. For example, three planets in D4 Cancer emphasizes emotional security needs and a strong connection to ancestry in domestic life. Multiple planets in D4 Capricorn suggests a structured, achievement-oriented approach to property and a sense of home that is earned rather than inherited.

Chaturthamsa Chart (D4)

The Chaturthamsa is the Vedic divisional chart for home, property, and inner happiness. Where your Rasi chart shows the surface of your domestic life, the D4 reveals the deeper karmic layer — what your soul requires to feel genuinely secure.

Deluxe Astrology's Chaturthamsa (D4) calculator divides each sign into four equal 7°30′ segments and maps all planets into their D4 positions using NASA JPL DE431 ephemeris — the divisional chart for analyzing home, property, vehicles, and the quality of inner happiness.

The Chaturthamsa: Deepening 4th House Karma

The 4th house in the Rasi birth chart governs home, mother, and inner contentment. The Chaturthamsa (D4) takes this analysis to a deeper level of precision. Each of the 12 Rasi signs is divided into four 7°30′ segments, and each planet's segment determines which of the 12 D4 signs it occupies. The resulting chart operates independently of the Rasi — a planet that appears strong in the Navamsa or weak in the Rasi may show entirely different qualities in the D4.

Reading the D4: Property, Mother, and Inner Peace

In D4 analysis, the Moon's placement reveals the emotional quality of your domestic life and your relationship with your mother — whether home feels like sanctuary or restlessness. Jupiter in a benefic D4 sign indicates property blessings and domestic expansion. Saturn in the D4 suggests that real estate and domestic security are areas that reward disciplined effort rather than luck. The D4 is also used in conjunction with the Dasha timing system — the Mahadasha lord's D4 sign is activated during its period, making property moves, home changes, and shifts in inner happiness more likely during those years.
