When is Mercury retrograde in 2027? The short answer
Mercury is retrograde three times in 2027: February 9 to March 3, June 10 to July 4, and October 7 to October 28. Each one starts in a water sign and backs into the air sign behind it: Pisces into Aquarius, Cancer into Gemini, Scorpio into Libra. Added together, Mercury spends about 67 days of 2027 retrograde, a little under a fifth of the year. All times below are UTC, so convert them before you circle a date.
| Retrograde (UTC) | Station degrees · shadow period |
|---|---|
| 1st: Feb 9, 17:35 to Mar 3, 12:34 | 5°58′ Pisces → 20°55′ Aquarius · shadow Jan 25-Mar 23 |
| 2nd: Jun 10, 18:18 to Jul 4, 19:40 | 6°21′ Cancer → 27°28′ Gemini · shadow May 26-Jul 19 |
| 3rd: Oct 7, 14:40 to Oct 28, 14:10 | 4°55′ Scorpio → 19°18′ Libra · shadow Sep 17-Nov 13 |
The three 2026 retrogrades, with their exact times, are on the Mercury retrograde 2026 dates page.
How the times were found: a station is the moment Mercury, seen from Earth, stops along the ecliptic and appears to reverse. It never really moves backwards; Earth and Mercury circle the Sun at different speeds, and the overtaking makes its path loop. Evening times in UTC can land on the next calendar day further east, so the February 9 start is already February 10 in East Asia and Australia. In the Americas it runs the other way: Mercury’s return to Scorpio at 00:26 UTC on November 10 is still November 9 there.
Why does every 2027 retrograde start in water and end in air?
Each 2027 retrograde sits on a sign boundary, so each has two halves: the first days in a water sign, the rest in the air sign just before it. Mercury’s retrograde loops creep backwards through the zodiac from one year to the next. In 2026 all three loops fitted inside Pisces, Cancer and Scorpio. By 2027 they have slipped far enough back that each one crosses into Aquarius, Gemini or Libra before Mercury turns direct.
The 2026 Pisces retrograde ran from 22° back to 8° Pisces. The 2027 one begins at 5°58′ Pisces, just below where that one stopped, and finishes at 20°55′ Aquarius.
In astrology, the water signs handle feeling, memory and attachment. The air signs handle words, ideas and the people you talk them over with. So a workable way to read 2027 is this: each retrograde opens with something felt and closes with something said, written or agreed. The first half stirs up an old feeling, and the second asks you to talk it through with someone.
When are the 2027 shadow periods?
The 2027 shadows run from January 25 to March 23, May 26 to July 19, and September 17 to November 13 (UTC). The pre-shadow begins when Mercury first reaches the degree where it will later turn direct. The post-shadow ends when it climbs back to the degree where it turned retrograde. In between, it crosses the same stretch of sky three times: forwards, backwards, forwards again.
The exact moments, in UTC:
- January 25, 18:58 to March 23, 15:00
- May 26, 06:04 to July 19, 08:42
- September 17, 07:27 to November 13, 09:55
Each shadow lasts roughly eight weeks, more than twice the length of the retrograde inside it. Take the first one. On January 25 Mercury reaches 20°55′ Aquarius for the first time. It runs on to 5°58′ Pisces, turns back to 20°55′ Aquarius, and only on March 23 does it reach 5°58′ Pisces again and leave the zone.
The practical use of the shadow is a notebook. Jot down what comes up in late January, late May and mid-September: the message you didn’t answer, the plan that stayed vague, the bill you meant to query. In astrological practice, those are the threads a retrograde comes back to.
What does each 2027 Mercury retrograde ask?
February 9 to March 3: from Pisces back into Aquarius
Mercury enters Pisces on February 1 at 01:26 UTC and stations retrograde on February 9 at 17:35, at 5°58′ Pisces. It slips back into Aquarius on February 18, turns direct on March 3 at 12:34 at 20°55′ Aquarius, and re-enters Pisces on March 18 at 10:02.
The first nine days or so belong to Pisces, the sign astrology ties to imagination, compassion and blurred lines. What goes wrong here is usually vagueness. Think of “we should do something soon” texts that nobody follows up, or a yes that meant maybe. A good habit for those days is to rewrite one vague sentence a day into a plain request.
From February 18 the retrograde is in Aquarius, the sign of friends, groups and shared plans, and in modern astrology of technology and networks too. This half suits rereading the group chat before you decide who agreed to what. It suits going back to a club, a team or a community project that stalled last year. Back up your phone and laptop before a big update.
June 10 to July 4: from Cancer back into Gemini
Mercury enters Cancer on May 28 at 17:07 UTC and stations retrograde on June 10 at 18:18, at 6°21′ Cancer. It backs into Gemini on June 26, turns direct on July 4 at 19:40 at 27°28′ Gemini, and returns to Cancer on July 12 at 13:45. This is the longest of the three in time, just over 24 days, yet it covers the shortest stretch of sky, under nine degrees.
Cancer covers home, family and the past. For the first two weeks, family history and household matters are the likely topics: a relative you haven’t rung in a year, a box of photos from your grandparents’ flat, the question of who looks after a parent.
After June 26 the tone turns practical and chatty, because Gemini rules siblings, neighbours, short trips and the daily stream of messages. Watch the family group chat, the sibling text you skimmed, the plan made with neighbours over the fence. This retrograde also opens the northern summer holidays. Travel can go ahead as planned. Leave some slack between connections, save your tickets and confirmations offline, and check the date on the return flight twice. Gemini is also the sign of learning, so a dropped course or a half-learned language is a good thing to pick back up.
October 7 to October 28: from Scorpio back into Libra
Mercury enters Scorpio on September 27 at 09:08 UTC and stations retrograde on October 7 at 14:40, at 4°55′ Scorpio. It moves back into Libra on October 16, turns direct on October 28 at 14:10 at 19°18′ Libra, and returns to Scorpio on November 10 at 00:26. At just under 21 days, it is the shortest retrograde of the year.
Scorpio is about trust, shared money and what goes unspoken. The first nine days suit an honest look at money you share with someone: a joint account, a loan between friends, the streaming subscriptions split four ways that nobody has checked in two years.
From October 16 the focus moves to Libra, the sign of partnership, agreements and fairness. That means the relationship itself, and agreements of every kind: who does which chores, the terms of a business partnership, a contract that comes up for renewal. Renegotiating an existing deal suits this retrograde well. A brand-new partnership agreement signed in a hurry suits it less. If the signing can wait until after October 28, let it wait. If it can’t, read every page and keep a copy.

What should you do, and not do, during Mercury retrograde?
Slow down whatever is hard to undo, and carry on with everything else. Mercury retrograde covers about 67 days of 2027, and life goes on through all of them. The traditional advice in astrology concerns things that are expensive or awkward to reverse. A large purchase is one. So is a lease signed the day you see the flat, a resignation email written at midnight, or a new phone bought the morning the old one freezes. If one of these has to happen during a retrograde, it can. Read the terms, sleep on it for a night, and keep the receipts.
Work, exams, appointments, planned trips and first dates all go ahead. A wedding booked for late June doesn’t need to move. What changes is the margin you leave yourself: set off ten minutes early, confirm the time the day before, read the message once more before you send it.
A handy test for what suits these weeks is the prefix “re”: review, reread, revise, repair, return, reconnect. Open the draft you abandoned, call the friend you keep meaning to call, go back over the decisions you made last quarter. Few times of year suit that kind of work better.

How do you see where Mercury retrograde falls in your chart?
Find the house of your birth chart that holds each retrograde’s degrees; in astrology, that is the part of life where the review lands. Put your birth date, time and place into the birth chart calculator, then look up these three ranges:
- February 9 to March 3: 20°55′ Aquarius to 5°58′ Pisces
- June 10 to July 4: 27°28′ Gemini to 6°21′ Cancer
- October 7 to 28: 19°18′ Libra to 4°55′ Scorpio
If a range falls in your 7th house, the retrograde reads as a partnership matter. In the 2nd house it points to money and possessions, and in the 10th to work and reputation. Because each 2027 retrograde crosses a sign boundary, it can touch two houses, one for each half. Then check whether any of your natal planets sit inside a range. Mercury crosses that point three times, and astrologers expect that retrograde to feel more personal.
Without a birth time the calculator leaves out the houses, but the planet check still works.
When each retrograde arrives, the Transits tab in the Euphia app shows it as it happens, under Now, This Week and This Month, read against your own birth chart.
Mercury retrograde 2027: frequently asked questions
Three times, in UTC: February 9 17:35 to March 3 12:34, June 10 18:18 to July 4 19:40, and October 7 14:40 to October 28 14:10. Each lasts about three weeks. Convert the times to your own zone, because in Asia and Australia some of these moments already fall on the next calendar day.
Every 2027 retrograde starts in a water sign and backs into an air sign: Pisces into Aquarius in February and March, Cancer into Gemini in June and July, Scorpio into Libra in October. In 2026 all three stayed inside water signs. Astrologers read the shift as feelings that now need to be put into words.
In UTC: January 25 to March 23, May 26 to July 19, and September 17 to November 13. The pre-shadow begins when Mercury first reaches the degree where it will later turn direct, and the post-shadow ends when it climbs back to the degree where it turned retrograde. Each shadow lasts about eight weeks.
On October 28, 2027 at 14:10 UTC, when Mercury turns direct at 19°18′ Libra. It returns to Scorpio on November 10 and leaves its post-shadow on November 13 at 09:55 UTC. There is no further Mercury retrograde before the end of 2027.
Don’t rush anything that is hard to undo, such as a large purchase, a contract signed in a hurry or an important message sent without rereading it. Everything else carries on as normal. The three-week stretches suit review: rereading, revising and returning to old threads.
Make your birth chart with your birth date, time and place, then find the houses that hold 20°55′ Aquarius to 5°58′ Pisces, 27°28′ Gemini to 6°21′ Cancer, and 19°18′ Libra to 4°55′ Scorpio. Because each 2027 retrograde crosses a sign boundary, it can touch two houses. Euphia’s Transits tab shows the retrograde against your own chart while it is happening.
