D60 Chart Calculator

A d60 chart calculator answers one of the finest-grained questions in Vedic astrology: not just which sign each planet occupies, but which sixtieth part of that sign, the Shashtiamsha, each planet falls in. The D60 chart divides every 30-degree sign into sixty 0.5-degree divisions, each carrying a traditional deity name, and classical texts treat it as the most microscopic divisional lens on a planet’s underlying strength and character. This free calculator computes the sidereal longitudes of the Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu and Ketu from real astronomy, then maps each planet into its amsha number, its D60 sign under the Parashara odd/even counting rule, and its presiding deity.

The calculation is deterministic and transparent. Your birth date, birth time, and timezone become a single UTC instant; each planet’s sidereal longitude is computed with a standard low-precision planetary theory minus the Lahiri ayanamsa; the degrees each planet has traversed within its sign decide the amsha; and the odd/even rule places it in the D60 chart. The tool loads with a worked example already rendered, so you can inspect real numbers before typing anything, and it states its conventions openly, including the one place where published editions disagree about the sixty deity names.

What is the D60 chart (Shashtiamsha)

Shashtiamsha is a Sanskrit compound meaning the sixtieth division: each rashi, or sign, is cut into sixty equal parts of half a degree each. It is one of the sixteen shodasavargas, the classical set of divisional charts described by Parashara in the Brihat Parashara Hora Shastra, and it is the finest of them. Where the birth chart (D1) shows the planets across twelve signs and the Navamsha (D9) divides each sign into nine, the D60 resolves each sign sixty times more finely, giving 720 divisions across the whole zodiac.

Tradition reads the D60 as a microscope on planetary strength. The classical teaching, summarized on the well-known reference pages for this varga, is that planets occupying benefic Shashtiamshas produce auspicious results while planets in malefic Shashtiamshas do the opposite, and that even a strong-looking planet can be undermined if it sits in a cruel division. Each of the sixty divisions carries the name of a deity, from Ghora, the terrible, through Kubera, the lord of wealth, to Chandra-Rekha, the streak of the moon, and the old texts treat these names as the presiding intelligences of the half-degree the planet occupies.

Because each amsha spans only half a degree, the D60 is extremely sensitive to birth time. The Moon crosses a full amsha roughly every hour, and the faster the planet, the quicker its amsha changes. This is why traditional astrologers insist that divisional charts, and the D60 above all, should only be trusted when the birth time is accurate, and why this calculator labels its date-only results as provisional. A few minutes of error in the recorded birth time can move a planet into a neighboring amsha with a different deity and a different D60 sign.

One honest framing note before you use the tool. The astronomical half of this page is computed with real orbital mechanics and checked against published data: the planetary longitudes, the Lahiri ayanamsa, and the amsha arithmetic are all verifiable numbers. The interpretive half, what it means for a planet to sit in the amsha of Sarpa or Saumya, belongs to astrology’s symbolic language, transmitted for centuries in the Jyotish tradition. Take what resonates, hold it lightly, and enjoy the precision of the calculation underneath it.

How to use this calculator

1. Enter your birth date. Pick the year, month, and day. Dates from 1900 to 2100 are accepted.
2. Enter your birth time as accurately as you know it. Each amsha spans only 0.5 degrees, so an accurate time is what makes the D60 meaningful. Hospital records and birth certificates beat family memory; rounded times like exactly 6:00 deserve a second look.
3. If you do not know the birth time, tick the date-only box. The tool then computes the planets for 12:00 noon local time and labels the whole chart PROVISIONAL, because the true amshas may differ.
4. Choose the timezone of the birthplace. Pick the nearest city from the dropdown, or choose “Custom UTC offset” and type the offset in hours if your city is not listed.
5. Check daylight saving. DST is not auto-applied. If the birthplace observed summer time on the birth date, adjust your time or enter the offset that was actually in effect, for example UTC+1 for a summer birth in London rather than UTC+0.
6. Press “Find my D60 chart.” The tool converts your birth time to UTC, computes the nine sidereal longitudes, derives each planet’s amsha, and places it in the D60 chart by the odd/even rule.
7. Read the spotlight. Your Moon’s amsha and deity, its D60 sign, and the most occupied D60 signs are summarized at the top.
8. Walk the tables. The planet table gives every graha’s sidereal position, amsha, D60 sign and deity; the twelve-sign grid shows which planets share each D60 sign; and the sixty-deity reference table lists every deity with the traditional meaning of its name.
9. Copy or print your result. The copy button saves a plain-text summary for your notes, and the print button produces a clean black-and-white version.

How this calculator computes your D60 chart

The calculation starts by turning your birth details into a single astronomical instant. Your birth date, birth time, and UTC offset are combined into a UTC timestamp, which becomes a day number d on the standard scale where d = 0 is 2000 Jan 0.0 UT. In date-only mode the tool uses 12:00 noon local time for this step and labels the result provisional.

Planetary positions come from the standard low-precision planetary theory: geocentric tropical longitudes for the Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn are computed from their orbital elements with the usual perturbation terms, then the Lahiri ayanamsa is subtracted to give the sidereal longitudes used in Vedic astrology. The linear Lahiri formula is ayanamsa = 23.85696 + (JD – 2451545.0) / 36525 x 1.396971 degrees, where JD is the Julian day of birth. Rahu is the mean lunar node, node = 125.1228 – 0.0529538083 x d degrees tropical minus the ayanamsa, and Ketu sits exactly opposite at Rahu + 180 degrees. This is the same verified engine core used across our Vedic calculators, accurate to a few arcminutes, which is ample for half-degree amsha work but not ephemeris grade.

The amsha number follows from the degrees each planet has traversed within its sign: amsha = floor(degrees within sign / 0.5) + 1, giving amsha 1 through 60. A planet at 15.0 degrees within its sign sits in amsha 31; a planet at 29.9 degrees sits in amsha 60. The D60 sign and deity then follow the Parashara rule quoted from BPHS chapter 6 on the standard reference pages: multiply the traversed degrees by 2 and divide by 12, and the remainder indicates the sign the Shashtiamsha falls in, while the sixty deity names run in their listed order for odd signs and in reverse for even signs.

In the tool’s arithmetic that rule becomes explicit. In an odd sign (Aries, Gemini, Leo, Libra, Sagittarius, Aquarius) the count runs forward from the sign itself: the first half-degree belongs to the sign itself, and D60 sign = sign((signIndex + amsha – 1) mod 12), with the deity being the amsha-th name in the list. So a planet in amsha 1 of Aries is in D60 Aries under the deity Ghora, and a planet in amsha 60 of Aries is in D60 Pisces under Chandra-Rekha. In an even sign (Taurus, Cancer, Virgo, Scorpio, Capricorn, Pisces) the count runs backward from the sign itself: D60 sign = sign((signIndex – (amsha – 1)) mod 12), with the deity being the (61 – amsha)-th name. So a planet in amsha 1 of Taurus is in D60 Taurus under Chandra-Rekha, and a planet in amsha 60 of Taurus is in D60 Gemini under Ghora. Because each sign’s sixty amshas cycle through all twelve signs exactly five times, every D60 sign is reachable from every natal sign.

The sixty deity names follow the BPHS-recompiled list, the edition most Jyotish software uses: Ghora, Rakshasa, Deva, Kubera, Yaksha, Kindara, Bhrashta, Kulaghna, Garala, Vahni, Maya, Purishaka, Apampathi, Marutwana, Kaala, Sarpa, Amrit, Indu, Mridu, Komala, Heramba, Brahma, Vishnu, Maheshwara, Deva, Ardra, Kalinasa, Kshiteesa, Kamalakara, Gulika, Mrityu, Kaala, Davagni, Ghora, Yama, Kantaka, Suddha, Amrita, PurnaChandra, Vishadagdha, Kulanasa, Vamshakshaya, Utpata, Kaala, Saumya, Komala, Sheetala, Karaladamshtra, Candramukhi, Praveena, Kaalpavaka, Dhannayudha, Nirmala, Saumya, Krura, Atisheetala, Amrita, Payodhi, Brahmana, and Chandra-Rekha. Other editions give different names at several positions, and the page below documents that variance openly rather than hiding it.

Worked example

Here is a worked example so you can see exactly what the tool computes. The tool loads with this example ready: birth date August 24, 1995, birth time 14:30, timezone Delhi, India (UTC+5:30).

First the time conversion. 14:30 at UTC+5:30 is 09:00 UTC on August 24, 1995, which is day number d = -1589.625 and Julian day 2449953.875. The Lahiri ayanamsa for that instant is 23.7961 degrees. The engine’s sidereal longitudes are: Sun 126.9493 (Leo 6.95), Moon 105.8181 (Cancer 15.82), Mars 177.1447 (Virgo 27.14), Mercury 149.6369 (Leo 29.64), Jupiter 222.4309 (Scorpio 12.43), Venus 127.8805 (Leo 7.88), Saturn 329.1026 (Aquarius 29.10), Rahu 185.5034 (Libra 5.50), Ketu 5.5034 (Aries 5.50).

Now the amshas. The Moon has traversed 15.8181 degrees of Cancer, an even sign, so amsha = floor(15.8181 / 0.5) + 1 = 32; counting backward, D60 sign = sign((3 – 31) mod 12) = Sagittarius, and the deity is the (61 – 32) = 29th name, Kamalakara. The full mapping is: Sun, amsha 14 of Leo, D60 Virgo, Marutwana; Mars, amsha 55 of Virgo, D60 Pisces, Kindara; Mercury, amsha 60 of Leo, D60 Cancer, Chandra-Rekha; Jupiter, amsha 25 of Scorpio, D60 Scorpio, Kantaka; Venus, amsha 16 of Leo, D60 Scorpio, Sarpa; Saturn, amsha 59 of Aquarius, D60 Sagittarius, Brahmana; Rahu, amsha 12 of Libra, D60 Virgo, Purishaka; Ketu, amsha 12 of Aries, D60 Pisces, Purishaka. Notice that Rahu and Ketu share the deity Purishaka but occupy different D60 signs, which the geometry forces: they sit 180 degrees apart with the same degrees traversed within their signs.

In the twelve-sign grid, Virgo holds the Sun and Rahu, Scorpio holds Jupiter and Venus, Sagittarius holds the Moon and Saturn, Pisces holds Mars and Ketu, and Cancer holds Mercury. In traditional lore, Mercury in the final amsha of Leo under Chandra-Rekha, the streak of the moon, is read as a softened, reflective finish to a fiery placement, while Mars in amsha 55 of Virgo under Kindara, the celestial musician, sits deep in the sign’s final degrees. As always, this is the symbolic layer for reflection; the astronomical layer, nine sidereal longitudes mapped by exact half-degree arithmetic, is the verifiable part.

How to read your result

Your result has four parts. First, the spotlight: your Moon’s amsha number, its natal sign and deity, its D60 sign, and the most occupied D60 signs in your chart, plus the ayanamsa value used. The Moon gets the spotlight because it moves fastest and its amsha is the most time-sensitive; if your birth time is even slightly off, the Moon’s amsha is the first thing that shifts.

Second, the planet table: all nine grahas with their sidereal sign and degree, amsha number out of 60, D60 sign, and presiding deity with the traditional meaning of the name. Read down the D60 sign column to see the shape of your divisional chart at a glance: clusters of planets in one D60 sign concentrate that sign’s themes in the microscopic layer, while an even spread diffuses them.

Third, the twelve-sign occupancy grid: a visual map of which planets fall in each D60 sign. Empty signs are marked empty; they are not bad, they simply carry no planetary tenant in this fine division. This grid is the quickest way to compare your D60 against someone else’s, or against your own birth chart’s sign placements.

Fourth, the sixty-deity reference table: every deity in odd-sign order with the traditional meaning of its name, so you can look up any amsha’s presiding name. Remember that for even signs the order reverses: amsha 1 of an even sign takes the 60th name, Chandra-Rekha, and amsha 60 takes the 1st name, Ghora. The meanings are classical name glosses, the terrible, the lord of wealth, the nectar of immortality, offered as symbolism rather than verdicts.

A few reading notes from the tradition. Planets in the early amshas of a sign sit near its beginning in the D60 cycle, while planets in the late amshas (55-60) have nearly completed the sixty-step journey through the zodiac within that one sign. The tradition pays special attention to planets in benefic versus malefic amshas: the old rule is that a planet in a benefic Shashtiamsha gives auspicious results and the reverse in a malefic one, with some teachers holding that even an exalted planet loses its luster in a cruel division. And because Rahu and Ketu always sit exactly opposite, they always share the same amsha number and, when their signs share odd/even parity, the same deity name, while never sharing a D60 sign.

The 60 Shashtiamsha deities and their traditional meanings

The deity list is the soul of the D60. Each half-degree division is said to be presided over by a named intelligence, and the names run a full emotional gamut: terror and poison (Ghora, Garala, Vishadagdha), death and time (Mrityu, Kaala, Yama), the great gods (Brahma, Vishnu, Maheshwara), gentleness and purity (Mridu, Komala, Suddha, Nirmala, Saumya), wealth and the waters (Kubera, Apampathi, Payodhi), and the moon in several forms (Indu, PurnaChandra, Candramukhi, Chandra-Rekha). The tool shows each name with its traditional gloss so the symbolism is legible even if you read no Sanskrit.

These meanings are lore, not predictions. A planet in the amsha of Mrityu, death, does not foretell anyone’s death; in the classical symbolic language it speaks of endings, transformation, and the gravity the planet carries in the fine layer of the chart. A planet under Saumya, the gentle and auspicious, is read as operating with a softer hand. The names are evocative on purpose: they give the astrologer a poetic vocabulary for the half-degree, the way the nakshatra names give a vocabulary for the Moon’s thirteen-degree mansions.

Now the honest complication: published editions of the sixty names do not fully agree. This tool uses the BPHS-recompiled list, the one most Jyotish software follows, verified against a full published rendering of BPHS chapter 6. But other respected editions differ at many positions. For example, one widely cited list gives Yama, Varuna, and Indra where this list has Purishaka, Apampathi, and Marutwana in the early divisions; gives Manda for the 30th amsha where this list has Gulika; gives Mukhya for the 42nd where this list has Vamshakshaya; and gives Shubha, Ashubha, and Bhramana in the late fifties where this list has Krura, Atisheetala, and Brahmana. If you compare this calculator against another source and a deity name differs, check which edition each source follows before concluding anything is wrong. The amsha numbers, the odd/even counting rule, and the D60 signs are stable across editions; it is the names that vary.

What this calculator does not do

Honest limits, stated plainly. This tool does not compute the D60 Lagna (ascendant): the ascendant needs the birthplace’s latitude, which is not collected, so only the nine planets are mapped. It uses a low-precision planetary engine, accurate to a few arcminutes, which is ample for half-degree amshas but not ephemeris grade; within a few arcminutes of an amsha boundary, a high-precision ephemeris could disagree on the amsha. In date-only mode the planets are pinned at local noon and the whole chart is labeled provisional, because the Moon crosses an amsha roughly every hour and the true birth-time amshas may differ. The deity names follow one edition of the classical list; other editions differ, as documented above, so cross-check the edition when comparing sources. Rahu and Ketu are the mean nodes, not the true osculating nodes; the two differ by up to about 1.5 degrees, which can matter near an amsha boundary. Finally, nothing here is a prediction: the deity meanings are centuries-old symbolic lore, and a single amsha never describes a whole life on its own.

Frequently asked questions

What is the D60 chart in Vedic astrology?

The D60 chart, or Shashtiamsha chart, is the sixtieth divisional chart of Vedic astrology. Each 30-degree sign is divided into sixty equal parts of 0.5 degrees, called amshas, giving 720 divisions across the zodiac. It is the finest of the sixteen classical shodasavargas described by Parashara, and tradition reads it as a microscope on each planet’s underlying strength, with every amsha presided over by a named deity.

How is the D60 chart calculated?

Take the degrees each planet has traversed within its sign and compute amsha = floor(degrees / 0.5) + 1, giving amsha 1 to 60. In odd signs (Aries, Gemini, Leo, Libra, Sagittarius, Aquarius) count forward from the sign itself: D60 sign = sign((signIndex + amsha – 1) mod 12). In even signs (Taurus, Cancer, Virgo, Scorpio, Capricorn, Pisces) count backward: D60 sign = sign((signIndex – (amsha – 1)) mod 12). The deity is the amsha-th name in the sixty-name list for odd signs, and the (61 – amsha)-th name for even signs.

Why does the D60 chart need an accurate birth time?

Because each amsha spans only half a degree. The Moon crosses one amsha roughly every hour, so a birth time that is off by an hour or two can put the Moon, and sometimes slower planets near boundaries, into the wrong amsha with the wrong deity and D60 sign. This calculator requires a birth time for full results and labels its noon-fallback date-only mode as provisional for exactly this reason.

What are the 60 Shashtiamsha deities?

The sixty deities are the presiding names of the sixty amshas, in odd-sign order: Ghora, Rakshasa, Deva, Kubera, Yaksha, Kindara, Bhrashta, Kulaghna, Garala, Vahni, Maya, Purishaka, Apampathi, Marutwana, Kaala, Sarpa, Amrit, Indu, Mridu, Komala, Heramba, Brahma, Vishnu, Maheshwara, Deva, Ardra, Kalinasa, Kshiteesa, Kamalakara, Gulika, Mrityu, Kaala, Davagni, Ghora, Yama, Kantaka, Suddha, Amrita, PurnaChandra, Vishadagdha, Kulanasa, Vamshakshaya, Utpata, Kaala, Saumya, Komala, Sheetala, Karaladamshtra, Candramukhi, Praveena, Kaalpavaka, Dhannayudha, Nirmala, Saumya, Krura, Atisheetala, Amrita, Payodhi, Brahmana, and Chandra-Rekha. For even signs the order reverses. The tool’s result page includes the full table with the traditional meaning of each name.

Why do different sources list different deity names for the D60 chart?

Because the classical sixty-name list survives in more than one edition, and they disagree at many positions. This calculator follows the BPHS-recompiled list used by most Jyotish software, while other respected editions give names like Yama, Varuna, Indra, Manda, Mukhya, Shubha, Ashubha, and Bhramana where this list has Purishaka, Apampathi, Marutwana, Gulika, Vamshakshaya, Krura, Atisheetala, and Brahmana. The amsha arithmetic and the odd/even counting rule are the same everywhere; only the names vary, so always check which edition a source follows before comparing.

Does this calculator show the D60 Lagna?

No. The D60 ascendant needs the birthplace’s latitude, which this calculator does not collect, so it maps only the nine planets: Sun, Moon, Mars, Mercury, Jupiter, Venus, Saturn, Rahu, and Ketu. Sign-only D60 work needs no birthplace, and the page states the omission openly rather than estimating an ascendant from incomplete data.

Is this d60 chart calculator free?

Yes, it is completely free and no account or signup is needed. Enter your birth date, birth time, and timezone to get each planet’s sidereal position, amsha number, D60 sign, and presiding deity, plus the twelve-sign occupancy grid and the sixty-deity reference table.
