Akshavedamsa (D45): the 45-fold paternal lineage chart explained, computed and read with classical citation
The Akshavedamsa, written as D45 in modern notation, is the paternal lineage chart in Parashari Vedic astrology. It is the dedicated divisional for paternal-line themes that extend beyond the immediate father to the broader paternal genealogy, completing the lineage pair alongside the D40 Khavedamsa.
The Akshavedamsa or D45 is the 45-fold harmonic division of the Vedic birth chart, used as the dedicated paternal lineage chart in Parashari astrology, paired with the D40 Khavedamsa for the complete lineage axis.
- Each 30-degree natal sign is divided into forty-five arcs of 0.667 degrees (40 arc-minutes).
- Movable signs start the count from Aries.
- Fixed signs start the count from Leo.
- Dual signs start the count from Sagittarius.
- Read for paternal lineage themes extending beyond the immediate father.
What the Akshavedamsa actually is
The Akshavedamsa, from aksha (axis or unchanging) and vedamsa (the part-of-Veda), is the chart produced by dividing each natal sign into forty-five equal arcs. The chart is the dedicated divisional for paternal lineage reading, paired with the D40 Khavedamsa for the complete lineage axis.
The 45-fold division and starting rule
Each 30-degree sign is divided into forty-five arcs of 0.667 degrees each. The modality-based starting rule:
- Movable signs start the count from Aries.
- Fixed signs start the count from Leo.
- Dual signs start the count from Sagittarius.

What the Akshavedamsa predicts
The chart is read for paternal lineage themes specifically. The Akshavedamsa lagna, the 9th house from the Akshavedamsa lagna, and Sun's Akshavedamsa placement together describe the structural register of the paternal-line inheritance. The reading is qualitative and is used alongside the D12 Dwadasamsa for the complete paternal-axis reading.
What the Akshavedamsa does NOT predict
Three boundary conditions. First, no timing predicted on its own. Second, extreme birth-time sensitivity (2.7 minutes of clock time per arc). Third, the chart is narrow in topical focus.

Frequently asked questions
What is the Akshavedamsa or D45 chart in Vedic astrology?
The Akshavedamsa, written as D45 in modern notation, is the 45-fold harmonic division of the Vedic birth chart used in Parashari Vedic astrology for paternal lineage reading. Each of the twelve 30-degree signs is divided into forty-five equal arcs of 0.667 degrees (40 arc-minutes) each. The chart extends the parents-reading of the D12 Dwadasamsa specifically to the paternal-line context, complementing the D40 Khavedamsa which covers maternal lineage.
How is the Akshavedamsa computed?
Each 30-degree sign is divided into forty-five equal arcs of 0.667 degrees each. The starting sign depends on the modality of the natal sign: movable signs (Aries, Cancer, Libra, Capricorn) count from Aries; fixed signs (Taurus, Leo, Scorpio, Aquarius) count from Leo; dual signs (Gemini, Virgo, Sagittarius, Pisces) count from Sagittarius. The three starting signs (Aries, Leo, Sagittarius) are the three fire signs, parallel to the Shodasamsa starting rule.
What does the Akshavedamsa chart actually predict?
The Akshavedamsa is read for paternal lineage themes specifically. The chart describes structural patterns originating from the father's side of the family, including inherited tendencies, family-line themes, and the chart's relationship to the broader paternal genealogy. The reading is qualitative and structural, supplementing the D12 Dwadasamsa's general parents-and-ancestry reading with paternal-specific texture.
How is the Akshavedamsa different from the Dwadasamsa for paternal reading?
The D12 Dwadasamsa reads parents and ancestry broadly with the 9th house axis for father. The D45 Akshavedamsa narrows the focus specifically to paternal lineage themes. The two are complementary: D12 gives the immediate father reading; D45 gives the extended paternal-line reading. Together with the D40 Khavedamsa (maternal lineage) they provide the complete lineage axis of the chart.
Why is the Akshavedamsa one of the most birth-time sensitive charts?
Each 0.667-degree arc corresponds to approximately 2.7 minutes of clock time at the ascendant in temperate latitudes. A birth-time error of 2.7 minutes can shift the D45 lagna by one arc. This makes the D45 one of the most birth-time-sensitive divisional charts, second only to the D60 Shashtiamsa (2 minutes per arc). Charts with unverified birth times produce D45 readings that should be treated as tentative.
What are the limits of the Akshavedamsa chart?
Three explicit limits. First, no timing predicted on its own. Second, extreme birth-time sensitivity (about 2.7 minutes of clock time per arc). Third, the chart focuses narrowly on paternal lineage themes and is best read alongside the D12 Dwadasamsa for the complete paternal-axis reading and the D40 Khavedamsa for the matching maternal-axis reading.
