Signs affected: the houses each retrograde touches
Every retrograde concerns all twelve signs, just not in the same place in the chart. Houses are counted from your Sun sign, which is your 1st house: each cell gives the house where Mercury stations retrograde, then the one where it turns direct. Your rising sign places them more precisely than your Sun sign alone.

What is a Mercury retrograde shadow period?
A retrograde does not start out of nowhere. Before it stations, Mercury moves forward through a stretch of the zodiac that it will then cover backwards, and a third time forwards. That stretch runs from the degree where it will turn direct to the degree where it stops to turn retrograde: for the February–March 2027 retrograde, from 20°55′ Aquarius to 5°58′ Pisces.
The pre-shadow begins when Mercury, still direct, reaches the first of these degrees: on January 25. The post-shadow ends when, after its direct station, it gets back to the degree where it had stopped: on March 23. This is geometry, the same perspective effect between Earth's orbit and Mercury's that produces the retrograde itself.
In astrological reading, the pre-shadow is often described as the time when the themes of the retrograde start to surface, and the post-shadow as the time when they settle. Treat these weeks as calendar markers, an invitation to reread, double-check and let things mature, rather than a forecast: the sky sets a rhythm, what you do with it is up to you.
How these dates are computed
Stations are dated to the minute when Mercury's apparent motion flips. Shadow boundaries are found on Mercury's longitude, narrowing the interval down to the minute it reaches the degree of the opposite station. Positions are tropical; depending on the ephemeris you check, a time may differ by a few minutes.
Frequently asked questions
When does the Mercury retrograde pre-shadow start in 2027?
On January 25 at 18:59 (20°55′ Aquarius), May 26 at 06:05 (27°28′ Gemini) and September 17 at 07:31 (19°18′ Libra), in UTC. Each time, Mercury reaches the degree where it will turn direct a few weeks later.
When does the Mercury retrograde post-shadow end in 2027?
On March 23 at 14:59 (5°58′ Pisces), July 19 at 08:44 (6°21′ Cancer) and November 13 at 09:56 (4°55′ Scorpio), in UTC. Each time, Mercury gets back to the degree where it stationed retrograde and leaves the shadow zone.
Which signs does Mercury retrograde through in 2027?
In February–March, from Pisces to Aquarius; in June–July, from Cancer to Gemini; in October, from Scorpio to Libra. Mercury stations retrograde in the first sign and turns direct in the second. Counted from your Sun sign, these signs fall in houses of your chart: the table of signs affected gives them for all twelve signs.
