Mercury, the planet known for its communication flair, isn’t officially retrograde until November 9th. However, starting October 21st, a kind of retrograde preview, referred to as retroshade, kicks in. This leads us right into a taste of its potential chaos.
The retrograde shadow consists of the two weeks before and after Mercury’s solar transit. These periods, called pre- and post-retrograde shadows, carry the same chaotic energy often experienced during retrograde movements. They provide opportunities for preparation and integration.
When does Mercury go retrograde?
Mercury officially starts its retrograde at 2:01 PM EST on November 9th, at 6°51 Sagittarius. Prior to that, on October 21, 2025, at 7:11 AM ET, it enters its pre-retrograde shadow at 20 degrees 42 Scorpio. After the retrograde, it will resume direct motion on November 29th, though its shadow phase continues until December 16th.
What is Mercury Retro Shade?
The retroshade phase occurs when a planet moves through the zodiac degree that marks its final forward position. As Mercury preps for its retrograde, these shadows can heighten anxiety, making unresolved feelings and emotional tensions feel even more pronounced. This, I think, can lead to overthinking and miscommunication.
When Mercury is retrograde, which typically lasts about three weeks, any unresolved issues highlighted during the pre-shadow phase tend to come to the forefront. Some enthusiasts liken this planetary event to a three-act play: the set-up (pre-shadow), the chaos (retrograde), and resolution (post-shadow).
How often does Mercury go retrograde?
This speedy planet, moving faster than any other in our solar system, retrogrades three to four times annually. When you account for its shadow periods, we might find ourselves dealing with its influence for up to six months each year.
When will Mercury go retrograde in 2025?
The upcoming retrograde through Scorpio and Sagittarius will mark the final Mercury retrograde event for 2025.
When is the next Mercury retrograde?
Looking ahead, the first Mercury retrograde of 2026 will be in Pisces, starting February 26 and continuing until March 20. Next year’s retrogrades will predominantly occur within water signs.
