When Saturn Mahadasha Ends, Mercury Begins

The nine lords run Ketu, Venus, Sun, Moon, Mars, Rahu, Jupiter, Saturn, Mercury, and then Ketu again. Saturn is late in the list. When its 19 years finish, Mercury does not negotiate. Mercury starts, with its own first antardasha, Mercury-Mercury. The length of that opening bhukti is 17 times 17, divided by 120, a bit over two years. People who expect a gentle fade of Saturn are describing a feeling. The calendar is a change of lord on a computed date, from the Moon's nakshatra balance.

You leave the houses Saturn occupies and rules. For Libra lagna that is a yogakaraka's exit, 4th and 5th, and it can feel like losing a support. For a lagna where Saturn rules the 8th, the exit can feel like a bind loosening. You enter whatever Mercury is doing: speech, trade, skill, and the houses Mercury owns. For Aries lagna Mercury owns the 3rd and the 6th. For Taurus, Mercury owns the 2nd and the 5th. The same handoff is a money-and-children story for Taurus and a courage-and-conflict story for Aries. Know the lagna or you will fear the wrong Mercury.

Saturn's transit over the Moon is independent of the mahadasha. You can leave Saturn mahadasha and still be in the middle phase of Sade Sati, Saturn on your Moon sign, or you can be free of Sade Sati and still have years of Saturn mahadasha left. Do not celebrate one clock as if it stopped the other. Saturday conduct can continue if the transit remains. The new chapter's graha is Mercury, whose day is Wednesday. Use Wednesday for Mercury's topics. Saturn has not left the natal chart. It has left the driver's seat.
