Seven years, and a feared reputation

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). Mars’s period runs seven years. Only the Sun’s six is shorter, and Ketu’s seven is the same length. Seven years is still a real stretch of a life: long enough to finish a degree, build a business, or build a home and settle into it.

Mars arrives with a heavier reputation than its length suggests. Much of that comes from Mangal dosha, the Mars placement rule used in marriage matching, and some of it comes from the classical texts themselves, which count Mars among the malefics. People who hear “Mangal dasha” often hear a warning in the same sentence.

This guide does for Mars what we did for the other planets in this series — Ketu, Rahu, Saturn, Jupiter, Venus, the Moon, Mercury and the Sun: 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 Mars’s turn comes — and why it always follows the Moon

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. Mars owns three: Mrigashira, Chitra and Dhanishta. The dasha order is fixed — Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury, and then Ketu again — so Mars always comes fifth, after the Moon and before Rahu.

If your birth Moon sat in Mrigashira, Chitra or Dhanishta, you were born inside a Mars Mahadasha, carrying only its unexpired balance — anything up to seven 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 Mars’s period does not come round again in a human lifetime.

For everyone else, Mars arrives in its fixed place, straight after the Moon. The age depends on which planet rules your birth nakshatra, because every period between that planet and Mars 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.

• Moon (Rohini, Hasta, Shravana) — Mars begins between birth and age 10.
• Sun (Krittika, Uttara Phalguni, Uttara Ashadha) — between ages 10 and 16.
• Venus (Bharani, Purva Phalguni, Purva Ashadha) — between 16 and 36.
• Ketu (Ashwini, Magha, Mula) — between 36 and 43.
• Mercury (Ashlesha, Jyeshtha, Revati) — between 43 and 60.
• Saturn (Pushya, Anuradha, Uttara Bhadrapada) — between 60 and 79.
• Jupiter (Punarvasu, Vishakha, Purva Bhadrapada) — between 79 and 95.
• Rahu (Ardra, Swati, Shatabhisha) — between 95 and 113, so almost no one with a Rahu birth nakshatra runs it.

What Mars is, and what the classical text says about its period

Mangala is the Sanskrit name for Mars, and “Mangal” is its everyday Hindi form; the word also means auspicious, and Tuesday, Mars’s weekday, is Mangalvar. The significations most often given for Mars are about force put to use: courage, initiative, physical energy, competition, younger siblings, land and property, and the skill of acting decisively.

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). It names the Sun, Saturn, Mars, the waning Moon, Rahu and Ketu as malefics. A later verse ranks four of them in rising order of malefic strength — the weak Moon, the Sun, Saturn, Mars — so Mars stands at the top of that list. The same text calls Mars male and makes it the ruler of fire among the five elements. That is the source of the reputation, and it is a real part of the tradition.

But the BPHS chapter on the effects of each Mahadasha does not describe Mars’s period as one result. It describes two. When Mars is strong — in its exaltation or own sign, in a kendra (an angular house: the 1st, 4th, 7th or 10th), or in the 11th or 2nd with strength, and with benefic company — the text lists gain of wealth and land, recognition by the government, conveyances, and happiness and good relations with co-borns (brothers and sisters). Strong in a kendra or the 3rd, it adds gain of wealth through valour and victory over enemies. It also says there may be some unfavourable effects at the end of the period. When Mars is debilitated, weak, or in the 6th, 8th or 12th house aspected by malefics, the text speaks of loss and distress.

The rule behind both lists comes earlier in the same chapter: the effects of a planet’s period follow its strength. A malefic planet is not a bad period by definition. For a strong Mars in a good house, the text lists land, recognition and victory over enemies.

Mars rules two signs, Mesha (Aries) and Vrischika (Scorpio). It is exalted — at its strongest — in Makara (Capricorn), deepest at 28°, and debilitated — at its weakest — in Karka (Cancer), the sign opposite. The first 12° of Mesha are its moolatrikona (a range of strength just below exaltation); the rest of Mesha is its own sign. Mars also has two special aspects: besides the full aspect every planet casts on the 7th house from itself, Mars casts full aspects on the 4th and the 8th.

A Mars Mahadasha is not Mangal dosha

These two are often mixed up, and the confusion causes needless worry. Mangal dosha (also called being manglik) is a placement rule: it asks which house Mars occupies in a birth chart, and it is used mainly in marriage matching. The placement stays the same for life, whichever Mahadasha a person is running.

A Mars Mahadasha is a period of time: seven years in which Mars’s own significations and the houses it rules in your chart come forward. You can be manglik and never run Mars’s period in your lifetime, and you can run Mars’s period without being manglik. One does not cause the other. Our guide to Mangal dosha covers that rule, its variations and its cancellations; this guide is only about the period.

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

• Mars–Mars — 0.41 years (4m 27d). The period states its own theme first, and briefly.
• Mars–Rahu — 1.05 years (1y 0m 18d). The third-longest. Ambition and the unfamiliar. Our Rahu guide covers that planet in full.
• Mars–Jupiter — 0.93 years (11m 6d). Learning, teachers, children and counsel.
• Mars–Saturn — 1.11 years (1y 1m 9d). The second-longest. Work, duty and patient effort — two malefics together, so the chart’s placement of each matters most here.
• Mars–Mercury — 0.99 years (11m 27d). Speech, study, trade and calculation.
• Mars–Ketu — 0.41 years (4m 27d). 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.
• Mars–Venus — 1.17 years (1y 2m 0d). The longest of the nine. Relationships, comforts and the arts.
• Mars–Sun — 0.35 years (4m 6d). The shortest. Authority, recognition and the father, briefly in focus.
• Mars–Moon — 0.58 years (7m 0d). The closing sub-period: home, the mother and the mind, and the bridge into Rahu’s eighteen-year Mahadasha.

Why your calculator and a printed table can disagree by about five weeks

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 Mars’s seven years the two conventions drift about 37 days apart — roughly five weeks — 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 Mars’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 Mars you get

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

The houses Mars rules. Mars rules Aries and Scorpio, so which houses those signs occupy 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 Karka (Cancer) lagna, Mars rules the 5th (children, intelligence, past merit) and the 10th (career, standing); for a Simha (Leo) lagna, the 4th (home, property, the mother) and the 9th (fortune, dharma — right conduct and duty). Ruling a kendra and a trikona (a house of fortune: the 1st, 5th or 9th) at once makes Mars a yogakaraka for those two lagnas — a planet the tradition reads as especially helpful — and the translator of the BPHS adds that Mars, as lord of the 2nd and 9th, is also very good for a Meena (Pisces) lagna. For a Mesha (Aries) or Vrischika (Scorpio) lagna, Mars rules the 1st house itself, so its period is about you. If you are in a Mars Mahadasha now, enter your birth details on our dasha page: it shows the houses Mars rules for your lagna and the house it sits in. Our guide to the twelve houses explains what each one governs.

Mars’s dignity. Mars in Makara, its exaltation, or in Mesha or Vrischika, its own signs, has firm ground to work from — the condition the BPHS ties to the good list above. Mars in Karka, its debilitation, is worth asking about: a debilitated planet still runs its full period, and other factors in the chart can lift it.

The house Mars sits in, and what it aspects. The BPHS ties the harder list to a Mars in the 6th, 8th or 12th aspected by malefics, and the better list to a Mars in a kendra, the 3rd, the 11th or the 2nd. Mars’s full aspects on the 4th, 7th and 8th houses from itself also bring those houses into its period.

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

What the seven years ask of you

If Saturn’s period rewards patience and Mercury’s rewards learning, Mars’s rewards effort aimed at a goal. Its themes — energy, initiative, property, competition — respond to action. A useful posture is to choose the thing worth the effort and do it: start the venture, take the exam, buy and repair the house, train the body.

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

Plan for the handover as well. Mars’s seven years always hand over to Rahu’s eighteen, and 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, charity, fasting on Tuesdays 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 houses does Mars rule for my lagna, and which house does it sit in; is it in Makara, Mesha, Vrischika or Karka; which planets sit with it or receive its aspect; which antardasha am I in and when does it turn; and what does my chart show for Rahu, who takes over when the seven 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.
