Shani (Saturn) mahadasha for Kanya (Virgo) 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 Saturn mahadasha lasts 19 years in full. Most people meet it partway through, so the part they live through can be shorter.

Saturn stands for time, duty, patience, hard work and structure. Its period tends to ask for steady effort and responsibility and repays it slowly but lastingly; shortcuts tend not to hold.

Counted from Virgo as the first house, Saturn rules Capricorn and Aquarius, your 5th and 6th houses. During its period the matters of both come forward:

The 5th house is children, study, creativity and romance. Its lord's period tends to favour learning, creative work, matters of children and decisions taken with a clear mind.

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.

Saturn counts Mercury, the lord of Virgo, 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 Saturn mahadasha, where the planet sits in your own chart and the sub-periods inside it shape the years more than your Moon sign alone.
