Chaturthamsa Chart (D4)

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.
