Mangal (Mars) mahadasha for Simha (Leo) 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 Leo as the first house, Mars rules Scorpio and Aries, your 4th and 9th houses. During its period the matters of both come forward:

The 4th house is home, mother, property, vehicles and peace of mind. Its lord's period tends to bring matters of the house and family to the front, including moves and changes at home.

The 9th house is luck, teachers, father, beliefs and long journeys. Its lord's period tends to bring guidance, higher learning, pilgrimage and a wider view of life.

Mars counts Sun, the lord of Leo, as a natural friend. That usually makes its period sit comfortably with your Moon sign: its themes arrive with support rather than friction.

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.
