In Western astrology, a planetary transit occurs when a planet moves from one zodiac sign to another and activates new energies, themes, and life experiences. Each planet travels at a different speed, so its influence can be short-term or long-lasting. Fast-moving planets affect daily moods and events, while slow-moving planets shape major life changes, personal growth, and long-term destiny patterns.

Transit effects are experienced globally, but their intensity and results vary based on an individual’s birth chart, house placements, and aspects. This is why planetary transits are one of the most important tools in predictive astrology.

☿ Mercury Transit (Approx. 14 to 30 Days per Zodiac Sign)

Mercury stays in a zodiac sign for roughly 2 to 4 weeks, depending on speed and retrograde motion. Mercury transits affect communication, thinking, learning, travel, business, and technology. During Mercury retrograde, the planet may move back and forth, causing it to remain longer in one sign and often bringing delays, revisions, and re-evaluation.
