Mercury retrograde is one of the most discussed astrological phenomena worldwide, and Korean astrologers have embraced it as a complement to traditional fortune practices. When Mercury appears to move backward in its orbit — roughly three to four times per year for about three weeks each — astrologers associate this period with disruptions in communication, technology, travel, and contracts.

What Happens During Retrograde

Mercury rules communication, intellect, and commerce. During retrograde, these areas may experience turbulence: emails go missing, misunderstandings multiply, electronics malfunction, and travel plans face unexpected delays. While skeptics see coincidence, millions worldwide — including many Koreans — use retrograde awareness to plan more carefully during these sensitive periods.

The Shadow Period

The effects of Mercury retrograde extend beyond its official dates. The "pre-shadow" period begins about two weeks before retrograde, as disruptions gradually intensify. The "post-shadow" lasts another two weeks after Mercury goes direct, as normalcy slowly returns. Experienced astrologers consider these shadow periods when planning important decisions or commitments.

Making the Most of Retrograde

Rather than fearing retrograde, view it as a productive period for reflection. Review past projects, reconnect with old friends, revise plans, and reconsider decisions. The "re-" prefix defines retrograde energy. Avoid signing new contracts or launching new ventures if possible.
