Six years — the shortest period of the nine

Vimshottari is the 120-year dasha system that divides a life into nine Mahadashas (major planetary periods), one for each of the nine grahas (planets, in the sense Jyotish — Vedic astrology — uses, which includes the two lunar nodes). The Sun’s period runs six years, the shortest of the nine. Ketu’s and Mars’s run seven; Venus’s, the longest, runs twenty. Six years is still a real stretch of a life: a first job and the first promotion, the years of a young child, or a move to a new city and the settling in.

The Sun’s reputation fits in one word: authority. Government, the father, status, recognition. That word is not wrong, but it leaves out most of what decides the period — which house the Sun rules in your chart, where it sits, and how strong it is by sign.

This guide does for the Sun what we did for Mercury, Ketu, Rahu, Saturn, Jupiter, Venus and the Moon: structure first, interpretation second. The structure — when the period arrives, how long it runs, what order its sub-periods take — is arithmetic, and you can check every figure. The interpretation depends on your chart, and we will show you which parts of it to look at.

When the Sun’s turn comes — and why it always follows Venus

Your first Mahadasha is read off the nakshatra (lunar mansion — one of twenty-seven equal 13°20′ divisions of the zodiac) that your Moon occupied at birth. Each nakshatra belongs to one of the nine dasha lords. The Sun owns three: Krittika, Uttara Phalguni and Uttara Ashadha. Each is the third star of a group of nine, so the Sun stands third in the dasha order: Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury, and then Ketu again.

If your birth Moon sat in Krittika, Uttara Phalguni or Uttara Ashadha, you were born inside a Sun Mahadasha, carrying only its unexpired balance — anything up to six years. Our guide to calculating the balance at birth shows how that remainder is worked out. The full cycle takes 120 years, so for you the Sun’s period does not come round again in a human lifetime.

For everyone else, the Sun arrives in its fixed place, straight after Venus. The age depends on which planet rules your birth nakshatra, because every period between that planet and the Sun has to run first. Add up those periods and you get the window below. The lower age is when the window opens if your birth lord had almost nothing left to run; the upper age, if it had its full term. For exact dates, our antardasha calculator gives all nine sub-period dates from the month your Sun period began, without a birth time.

• Venus (Bharani, Purva Phalguni, Purva Ashadha) — the Sun begins between birth and age 20.
• Ketu (Ashwini, Magha, Mula) — between ages 20 and 27.
• Mercury (Ashlesha, Jyeshtha, Revati) — between 27 and 44.
• Saturn (Pushya, Anuradha, Uttara Bhadrapada) — between 44 and 63.
• Jupiter (Punarvasu, Vishakha, Purva Bhadrapada) — between 63 and 79.
• Rahu (Ardra, Swati, Shatabhisha) — between 79 and 97.
• Mars (Mrigashira, Chitra, Dhanishta) — between 97 and 104, so almost no one with a Mars birth nakshatra runs it.
• Moon (Rohini, Hasta, Shravana) — not before 104. A Moon birth nakshatra places the Sun’s period at the very end of the 120-year cycle, beyond a normal life.

What the Sun is: a malefic, and a mild one

Surya is the Sanskrit name for the Sun; Ravi and Aditya are two others you will meet in charts and texts. Like the Moon, the Sun never turns retrograde, and the sign it occupies at birth follows the calendar: it moves through one sign in about a month.

The significations most often given for the Sun are about standing and source: the father, authority and government, status and recognition, vitality and the body’s strength, and the sense of self. That is where the one-word summary comes from.

The Brihat Parashara Hora Shastra (BPHS), the foundational text of the tradition, sorts the grahas into benefics (planets that tend to give) and malefics (planets that tend to test). One verse names Jupiter and Venus as benefics and the Sun, Saturn and Mars as malefics; elsewhere the text adds the waning Moon, Rahu and Ketu to the malefics. That verse then ranks its malefics by the strength of that tendency, mildest first: the weak Moon, the Sun, Saturn and Mars. So in that ranking only the weak Moon is milder than the Sun. “Malefic” here describes a tendency, not a verdict on six years of your life.

The Sun rules one sign only, Simha (Leo). It is exalted — at its strongest — in Mesha (Aries), and debilitated — at its weakest — in Tula (Libra); the translator’s notes to the BPHS place its weakest point at the 10th degree of Libra. In Simha, the first 20° are its moolatrikona (a zone of strength just below exaltation) and the rest its own sign. The translator’s table of natural relationships gives the Sun three friends — the Moon, Mars and Jupiter — two enemies, Venus and Saturn, and one neutral, Mercury.

The nine sub-periods inside Surya Mahadasha, in order

A Mahadasha is divided into nine antardashas (sub-periods, also called bhukti), one for each of the nine lords. If the idea is new, our short explainer on what an antardasha is covers it. The order follows one rule: the Mahadasha opens with its own lord’s sub-period, then continues through the Vimshottari cycle.

So the Sun’s period runs Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury, Ketu, Venus. Each length is the Mahadasha’s six years multiplied by the sub-lord’s own years, divided by 120, so every figure is arithmetic and the nine sum to exactly six years. Because the Mahadasha is short, so is every sub-period inside it: none runs longer than a year. The year-month-day forms use the 360-day dasha year (twelve 30-day months) that many printed tables use.

• Sun–Sun — 0.30 years (3m 18d). The shortest of the nine. The period states its own theme first, and briefly.
• Sun–Moon — 0.50 years (6m 0d). Home, the mother and the mind. Our Moon guide covers that planet in full.
• Sun–Mars — 0.35 years (4m 6d). Energy, initiative, property and siblings.
• Sun–Rahu — 0.90 years (10m 24d). Ambition and the unfamiliar. Our Rahu guide covers that planet.
• Sun–Jupiter — 0.80 years (9m 18d). Learning, teachers, children and counsel.
• Sun–Saturn — 0.95 years (11m 12d). The second-longest: work, duty and patient effort. Saturn is one of the Sun’s two natural enemies in the translator’s BPHS table.
• Sun–Mercury — 0.85 years (10m 6d). Speech, study, trade and accounts.
• Sun–Ketu — 0.35 years (4m 6d). A quieter stretch; Ketu’s themes of letting go and inquiry. The same length as the Mars sub-period, because Mars and Ketu both have seven years.
• Sun–Venus — 1.00 year (1y 0m 0d). The longest of the nine, and the closing sub-period: relationships, comforts and the arts, and the bridge into the Moon’s ten-year Mahadasha. Venus is the other of the Sun’s two natural enemies in that table.

Why your calculator and a printed table can disagree by about a month

If you compare dates from two sources you will sometimes find them weeks apart, and the reason is not an error in either. The Vimshottari texts give each period in years; they do not settle, in a way every school accepts, how many days a dasha year contains. Many printed tables use a 360-day year, the figure behind the year-month-day forms above. Our antardasha calculator and the dasha table in your Kundali (birth chart) count a dasha year as 365.25 days, the length of a calendar year.

Over the Sun’s six years the two conventions drift about 31 days apart — roughly a month — so the last sub-periods differ most. A table that counts every period since your birth in 360-day years drifts further still, about five days for each year you have lived, so even the date the Sun’s period begins can differ by months. Compare dates from one source with dates from the same source, and ask which convention an astrologer uses before you plan around a turning point.

The chart decides which Sun you get

Three things in your own chart do most of the work, and all three can be read from a Kundali.

The house the Sun rules. The Sun rules Simha (Leo) alone, so which house it governs depends on your lagna (ascendant, the sign rising at birth). A Mahadasha delivers the matters of the houses its lord rules as well as the house it sits in. For a Simha lagna, the Sun rules the 1st house itself, so its period is about you. For a Mesha (Aries) lagna, it rules the 5th (children, learning, judgement); for a Vrischika (Scorpio) lagna, the 10th (career and public standing); for a Kanya (Virgo) lagna, the 12th (expense, distance, retreat). If you are in a Sun Mahadasha now, enter your birth details on our dasha page: it can show the house the Sun rules for your lagna and the house it sits in. Our guide to the twelve houses explains what each one governs.

The Sun’s dignity. The Sun in Mesha, its exaltation, or in Simha, its own sign, has firm ground to work from. The Sun in Tula, its debilitation, is worth asking about — a debilitated planet still runs its full period, and other factors in the chart can lift it. Its company matters too: with its friends the Moon, Mars or Jupiter, or with Venus or Saturn, the two the text counts its enemies.

The planets close to it. A planet very near the Sun in the sky is called combust (asta), and astrologers ask whether it keeps its own strength in that position; schools give different distances for each planet. Mercury, which never strays far from the Sun, sits with it so often that the pair has its own name, Budha-Aditya yoga (a yoga here is a named planetary combination). In the Sun’s period, those close planets are worth asking about as well.

Put those together and the question “is Sun Mahadasha good?” turns into a better one: which house does the Sun rule for my lagna, which house and sign does it sit in, and which planets sit close to it? Our beginner’s guide to reading your Kundali shows how to find each of these in your own chart.

What the six years ask of you

If Saturn’s period rewards patience and Mercury’s rewards learning, the Sun’s rewards taking responsibility. Its themes — standing, duty to those who depend on you, the work you are known for — respond to steady, visible effort. A useful posture is to own your role: take the position you have earned, keep your word, look after your health, and give the elders in your life their due.

Expect ordinary hard months too. The Sun’s period contains sub-periods of Saturn, Rahu, Ketu and Mars, still runs through the house the Sun rules in your chart, and still meets transits that run on their own clocks. A hard year inside Surya Mahadasha does not mean the period has failed, and a good one is not luck against the odds. Both are the chart doing what charts do.

Plan for the handover as well. Six years pass quickly, and the Sun always hands over to the Moon’s ten. The months either side of a change of Mahadasha are read as a junction in their own right — our guide to dasha sandhi explains how.

On remedies, the tradition is not uniform. Mantra recitation, offering water to the rising Sun, charity, fasting and gemstones all appear in different regions and lineages, and they do not agree with one another. They are matters to raise with someone reading your actual chart, in your own tradition. A source that promises a specific outcome from a specific stone, or warns of ruin without one, has gone beyond what the classical texts support.

The best preparation is to arrive at a reading with the right questions: which house does the Sun rule for my lagna, and which house does it sit in; is it in Mesha, Simha or Tula; which planets sit close to it; which antardasha am I in and when does it turn; and what does my chart show for the Moon, who takes over when the six years end. Every one of those can be asked of your own chart rather than a general description — and you can ask Jyothshi all of them.
