Mercury Retroshade Is the Astrology Concept You Haven’t Heard of Yet
If you follow astrology at all, you already know Mercury retrograde. It dominates social media feeds a few times a year, gets blamed for everything from crashed laptops to botched text messages, and has become a cultural shorthand for “things going sideways.” But there’s a lesser-known phase wrapped around each retrograde that astrologers say deserves just as much attention, and it goes by a name most people haven’t encountered: retroshade.
What It Is
The concept of “retroshade” refers to Mercury’s retrograde shadow period, which occurs both before and after a Mercury retrograde, according to The Cut. The term was coined by astrologer Lisa Stardust after she observed that the pre- and post-retrograde phases can be more complex than the retrograde itself, as reported by Vogue.
That observation is the piece that changes the picture. Most people treat Mercury retrograde as a single event with a clear start and end date. Stardust’s framework suggests the full cycle is longer and more layered than that, stretching weeks beyond the retrograde window most people track.
How the Three Phases Work
The full Mercury retrograde cycle is often described as a three-part sequence consisting of the pre-shadow phase, the retrograde period, and the post-shadow phase. Each one covers the same range of zodiac degrees, but the energy and function differ.
During the pre-retroshade period, Mercury begins moving through degrees it will later revisit during the retrograde and post-retrograde phases. This phase is associated with early developments of issues that will unfold more fully during the retrograde. Think of it as the setup: themes start surfacing, conversations begin, and situations take shape without necessarily reaching resolution.
The retrograde itself occurs when Mercury appears to move backward, during which time previously emerging issues are addressed. This is the phase most people already know. Miscommunications, delays, old contacts resurfacing — the familiar retrograde territory.
Then comes the post-retroshade period, when Mercury returns to those same degrees for a third and final time. This phase is associated with gaining additional information and making final decisions related to matters that surfaced during the earlier phases. Where the pre-retroshade plants seeds and the retrograde stirs them up, the post-retroshade is where clarity arrives and choices get made.
The Current Cycle’s Timeline
For the current cycle, the pre-retroshade occurred from February 11 to February 26, followed by the Mercury retrograde from February 26 to March 20. The post-retroshade period in Pisces runs from March 20 to April 9.
That means the full cycle spans nearly two months, from early February through the first week of April. If you were only watching the February 26 to March 20 retrograde window, you were tracking roughly three weeks of a much longer arc.
How to Use This
If you want to apply the retroshade framework to your own life, here’s what you can do with it.
Start by looking back at the pre-retroshade window (February 11 to February 26 for the current cycle). What themes came up during that stretch? What conversations started? What felt like it was beginning to shift? Those threads likely ran through the retrograde and may still be unfolding now.
During the post-retroshade period (March 20 to April 9, currently in Pisces), pay attention to whether you’re receiving new information about those same themes. According to the framework, this is the window for final decisions and resolution on matters that have been in motion since mid-February.
Going forward, you can track retroshade periods for future Mercury retrogrades the same way. The pre-shadow begins when Mercury first enters the degrees it will later retrograde through. The post-shadow ends when Mercury clears those degrees for the last time. Most astrology apps and sites now list shadow period dates alongside retrograde dates — look for “shadow” or “retroshade” in the details.
