Mahadashas

Mercury mahadasha (17 years)

Mercury's seventeen years close the Vimshottari cycle with a period of the mind: learning, trade, writing, networking and practical intelligence. Mercury takes on the colour of the planets it joins, so its period depends unusually strongly on its company.

Lengths from the JyotiSoft engine's Vimshottari timeline (sidereal year). Months and days are twelfths and thirtieths of the dasha year, as dasha tables write them; the exact dates in your chart depend on the Moon's degree at birth.

What the period is about

Mercury signifies speech, writing, commerce, mathematics, analysis, youth and friends. Its period often brings study, a business, a career in communication or technology, contracts and a busy social and professional network. People tend to think faster and juggle more in a Mercury dasha.

What decides the results

Mercury is strong in Gemini and exalted in Virgo; in Pisces it is debilitated. It is often combust because it stays close to the Sun, which can make its period more about effort than ease. Mercury mirrors its company: with Jupiter or Venus it becomes benefic, with Mars or Saturn more demanding. For Taurus, Gemini, Virgo, Libra and Capricorn ascendants it rules helpful houses; for Aries, Cancer and Scorpio it rules difficult ones.

The antardashas

Mercury/Mercury opens with almost two and a half years. Mercury/Venus is the longest sub-period, nearly three years, and is traditionally one of the best: two friends, bringing comfort, art and profitable work together. Mercury/Ketu can bring a pause or a change of field. Mercury/Moon combines two rivals and is watched for nervousness; Mercury/Saturn usually brings steady, practical progress.

Living it well

Learning is the best use of the period: a skill, a language, a qualification, a business that needs analysis. The mind needs rest as much as stimulation, so screens off at night is modern Mercury advice. Traditional remedies include Wednesday observances and the worship of Vishnu; the tradition gives an emerald when the whole chart supports it.
