How to read Mercury transits
Mercury is never far from the Sun and spends about 14 to 30 days in a sign, longer around its three or four retrograde periods each year. It can re-enter a sign it has just left.
Mercury rules speech, intellect, commerce, writing and travel. Its transit is read for communication, contracts, study and trade.
Pay closest attention to the dates marked retrograde. Many astrologers avoid signing major agreements or starting new ventures while Mercury is retrograde.
These Mercury gochar dates for 2018 use Lahiri ayanamsa and true lunar nodes. For dasha–transit interpretation relative to a birth chart, book a personal reading.
Planet Transit FAQ
How Vedic gochar timings are calculated and how to read this table.
What is planetary transit (gochar) in Vedic astrology?
Gochar is the current movement of the Navagraha through the sidereal zodiac. When a planet crosses into a new rashi, that exact local datetime is the transit (ingress) timing used for timing analysis.
Which ayanamsa do you use?
All positions use the Lahiri (Chitrapaksha) ayanamsa — the same system as our daily Panchang — so Sun and Moon signs stay consistent across tools.
Does my city change planet positions?
Geocentric sidereal longitudes are the same worldwide at a given UTC instant. Your city only converts that instant into local clock time (with DST when applicable).
Are Rahu and Ketu mean or true nodes?
We use true lunar nodes for Rahu and Ketu. Ketu is always opposite Rahu (180° apart).
How accurate are these timings?
Ingress times are computed with modern astronomical models and refined to about one second. Outer planets usually agree with major panchangs within minutes; Moon and nodes can differ slightly between softwares. Use them for planning; verify ritual-critical muhurta separately if needed.
