Mangal (Mars) mahadasha for Mithuna (Gemini) Moon sign

In the Vimshottari system a life moves through nine long periods, each ruled by one planet. The planet that rules the period sets the tone of those years: the areas of life that come forward, and the kind of effort that pays.

The Mars mahadasha lasts 7 years in full. Most people meet it partway through, so the part they live through can be shorter.

Mars stands for energy, courage, drive, land and brothers. Its period tends to be active and direct: a time to start things, compete and defend what matters, best used with a cool head.

Counted from Gemini as the first house, Mars rules Scorpio and Aries, your 6th and 11th houses. During its period the matters of both come forward:

The 6th house is daily work, service, competition and debts. Its lord's period tends to bring hard work and rivals to deal with, and favours steady routines and paying down what you owe.

The 11th house is income, gains, friends and hopes. Its lord's period tends to bring returns on earlier effort, helpful networks and wishes moving closer.

Mars counts Mercury, the lord of Gemini, as a natural enemy. Its themes may meet some friction with your temperament, so patience and a steady routine help the period give its best.

Which mahadasha you are in, and when it began, depends on the Moon's nakshatra at the moment you were born, so it is personal to you. Even within the Mars mahadasha, where the planet sits in your own chart and the sub-periods inside it shape the years more than your Moon sign alone.
