Antardasha 7 of 9 in Mercury mahadasha · 2 yrs 6 mo
Mercury-Rahu antardasha बुध-राहु अंतर्दशा
Mercury-Rahu lasts about two years, six months, and eighteen days. Rahu, modelled on Saturn, is a friend of Mercury, and Mercury returns it, so tradition reads this as the period's most ambitious stretch: technology, foreign trade, media, and clever strategy prosper. Sudden gains through unconventional commerce are listed. The cautions are cunning that becomes dishonesty, speculation, and nervous exhaustion. Contracts with foreign parties need care. Productive but easily overreached.

The mahadasha behind it
Mercury mahadasha is a seventeen year period that tradition associates with intellect, communication, commerce, learning, and adaptability. After the heavy Saturn period it feels lighter, quicker, and more social. Classical texts read a strong Mercury as bringing success in trade, writing, and study, and a wide network of useful contacts, while a weak or afflicted Mercury brings nervous strain, scattered effort, and losses through miscommunication.

What Rahu adds as sub-lord
Rahu mahadasha is an eighteen year period that tradition associates with ambition, unconventional paths, foreign lands, and the hunger for what one does not yet have. After the direct Mars period it feels more complicated and less predictable. Classical texts read a well-placed Rahu as bringing worldly rise by unusual routes, and an afflicted Rahu as bringing confusion, deception, and dissatisfaction despite gains. As an antardasha lord it colours the mahadasha's agenda rather than replacing it: the houses Rahu owns and occupies in the birth chart become the stage for Mercury's themes for 2 yrs 6 mo. See Rahu as a mahadasha.
How the length is computed
Mercury runs 17 years and Rahu runs 18 years in the 120-year cycle, so Mercury-Rahu lasts 17 × 18 ÷ 120 = 2.550 years, about 2 yrs 6 mo. The exact calendar boundaries depend on the Moon's degree at birth; the free kundli lists them.
