D60 Chart Calculator: Free Shashtiamsha Chart with Deities

What is the D60 chart (Shashtiamsha)?

Shashtiamsha means "sixtieth part". The D60 chart divides each 30-degree sign into 60 equal parts of half a degree (30 arcminutes). Brihat Parashara Hora Shastra lists it as the last and finest of the sixteen divisional charts (shodasha varga) and gives every one of the 60 parts a name, from Ghora ("terrible") to Chandrarekha ("a line of the Moon").

Two things make the D60 special. First, Parashara gives it the largest share of a planet's strength in the Vimshopaka scheme (4 of 20 points in the sixteen-chart version), more than the birth chart itself. Second, each part carries a quality: shubha (benefic) or krura (cruel). BPHS 6.41 says a planet in a shubha part gives auspicious results, while a planet in a krura part destroys the good it would otherwise give. That is why astrologers check the D60 before trusting a strong-looking planet in the birth chart.

Parashara assigns the D60 to "all indications" rather than one area of life. Modern teachers, especially in the Jaimini tradition, read it for deep karma carried over from past lives. That reading is later practice, and this page labels it as such.

How the D60 is calculated

BPHS 6.33 gives the rule: take the planet's degrees within its sign, multiply by two, divide by twelve and add one to the remainder. In practice:

1. Find the planet's degree inside its sign, for example 13°36' of Aries.
2. Double it and drop the fraction: 13.6 × 2 = 27.2, so the planet sits in part 28 (counting from 1).
3. Count 27 signs forward from the sign itself, starting at Aries as zero. 27 signs is two full rounds plus 3, so the D60 sign is Cancer.
4. Name the part. Aries is an odd sign, so read the deity list in order: part 28 is Kshitisha, a shubha part.

The deity order flips for even signs (Taurus, Cancer, Virgo, Scorpio, Capricorn, Pisces), as BPHS 6.40 says. The first half degree of Aries is Ghora, while the first half degree of Taurus is Chandrarekha. This is the single most common mistake in D60 tables online: many list one order for all twelve signs.

This calculator uses the "traditional, from sign" method, which is also the default in Jagannatha Hora and its open-source port PyJHora. Some software counts from Aries instead, which gives different D60 signs, so compare like with like if you check another tool.

The 60 shashtiamsha deities

Names follow BPHS 6.34 to 6.39. Read the first column for odd signs and the last column for even signs. The shubha and krura labels follow the Jagannatha Hora classification; four names whose meaning sounds harsh (Bhrashta, Kantaka, Kulanasha, Krura) are treated as benefic in that list and other commentators disagree, so they are marked disputed.

Of the 60 parts, 33 are shubha, 23 krura and 4 disputed in this scheme. A random planet therefore lands in a benefic part a little more often than not, which is worth remembering before reading too much into one krura placement.

How long does a D60 lagna last?

A sign takes about two hours to rise, so a half-degree D60 part rises in under two and a half minutes. We timed every sign with the Swiss Ephemeris for Delhi and Chennai. In north India a Pisces or Aquarius rising sign gives you less than a minute and a half per D60 lagna:

That is why the calculator scans your birth time ten seconds at a time and tells you exactly how many minutes your D60 lagna holds before and after the recorded time. The planets' shashtiamshas change far more slowly (the Moon takes about an hour to cross half a degree, the slow planets days or weeks), so the deities of the planets stay trustworthy even when the D60 lagna and houses do not.

How to read your D60, step by step

1. Check the reliability banner first. If your D60 lagna changes within two minutes either side, read only the planets' deities and natures.
2. Read the shubha and krura balance. Planets in shubha parts deliver their promise more easily; planets in krura parts bring their results through effort and harder lessons.
3. Cross-check strong planets. An exalted or own-sign planet in the birth chart that falls in a krura shashtiamsha is weaker than it looks. A debilitated planet in a shubha part often surprises on the upside.
4. Look at the lagna lord and the Atmakaraka. In Jaimini practice the Atmakaraka's D60 placement shows the soul's deepest lesson. Find yours with the Atmakaraka calculator.
5. Note vargottama planets. A planet in the same sign in the D1 and D60 is consistent at every level of the chart and acts with unusual steadiness.
6. Time it with the dasha. A planet's shashtiamsha colours the whole of its mahadasha and antardashas. Check your running period with the dasha calculator.

D60 and the other divisional charts

Each varga answers a narrower question. The D9 Navamsa shows marriage and a planet's inner strength, the D10 Dasamsa shows career and the D11 Rudramsha shows gains and wealth. The D60 sits underneath all of them as a quality check on every planet. A good rule of thumb: when the D1, D9 and D60 agree about a planet, its results are reliable; when the D60 disagrees, expect the results to come with conditions.

What this calculator cannot do

• It cannot fix a wrong birth time. If your D60 lagna is unstable, a birth-time rectification by an experienced astrologer comes first.
• It does not predict events. Shashtiamsha deities describe the quality of a placement, not dates or outcomes.
• It does not settle the disputed parts. Where commentators disagree, the page says so instead of picking a side silently.
• It uses Lahiri ayanamsa and the traditional from-sign method. Other ayanamsas or methods give different D60 charts.
