In Vedic astrology, Mercury (Budha) Mahadasha lasts for 17 years under the Vimshottari Dasha system. Mercury is traditionally associated with intelligence, communication, speech, business, mathematics, analysis, writing, trade, technology, learning, networking, negotiation and adaptability.
Mercury Mahadasha can become an important period for developing the mind, building professional skills, expanding communication networks and creating income through knowledge and business.
The period can be especially significant for people working with:
Technology + Business + Communication + Data + Education + Trade
However, Mercury is highly adaptable, so its expression depends strongly on the planet it is associated with and the house in which it is placed.
The actual results depend on Mercury's house, sign, Nakshatra, dignity, house lordship, conjunctions, aspects, retrograde status, planetary strength, divisional charts, yogas and the Antardasha operating within the 17-year period.
Mercury should therefore always be interpreted in the context of the complete Kundli.
