Mercury Retrograde and the Zodiac Signs

When Mercury enters retrograde motion within the range of dates for a given astrological sign, be wary of the listed effects.

IN AQUARIUS (Jan 20–Feb 18): With Mercury retrograde in Aquarius, the sign 
that governs relationships, 
friendships are put at risk. Petty 
squabbles, misunderstandings, and miscommunications abound. Know who your friends are.

IN PISCES (Feb 19–Mar 20): Foggy thinking,
 daydreams, and escapism are 
the norm; day-to-day realities
 confound otherwise clear heads
 when Mercury, the planet that rules logic, is in Pisces, which governs illusion. Practice creative pursuits—writing, dancing, photography, film, or painting.

IN ARIES (Mar 21–Apr 19): Expect to be frustrated and frazzled. Assertive,
 impulsive Aries wants to move
 ahead, and all of the energy is going backward. Watch what you say and how you say it. Pay attention to what people say to you; you might be pleasantly surprised.

IN TAURUS (Apr 20–May 20): Take time to formulate your thoughts. Taurus, an unhurried sign, slows down the 
mental processes. He also governs banking, so delay money matters. Review financial matters, and position yourself for growth.

IN GEMINI (May 21–Jun 20): Because Gemini 
rules communications, be prepared for miscommunications
 when Mercury is in this sign. Expect lots of phone calls or none, and lost or misplaced mail. You may not articulate clearly, and gossip abounds. Old friends may reconnect.

IN CANCER (Jun 21–Jul 22): Expect annoyances 
at home with baking, gardening,
 and household duties under domesticated Cancer. Complete repair projects that weren’t finished or done correctly.

IN LEO (Jul 23–Aug 22): Avoid speculative investments. It is not a good time to
 buy and sell or do any trading.
 Instead, analyze your investment
 portfolio. Use your know-how and advisory skills to help friends and associates.

IN VIRGO (Aug 23–Sep 22): Challenging situations arise, especially in the 
workplace. Expect product delays and equipment breakdowns,
 as well as crankiness among coworkers under finicky, detail-oriented Virgo. Double-check your work before you call it finished.

IN LIBRA (Sep 23–Oct 22: Accept your physical
 attributes; do not have a makeover. Indecision reigns, so limit
 purchases—or risk returning
 them. Libra, representing beauty, grace, charm, and diplomacy, is out of balance. Refresh, relax, and rejuvenate.

IN SCORPIO (Oct 23–Nov 21): Emotions rule—not common sense—so beware.
 Avoid affairs of the heart. Passionate Scorpio is also secretive, 
and your secrets may seep out. Keep them in a diary.

IN SAGITTARIUS (Nov 22–Dec 21): It is not a time 
to travel, so reschedule or expect
 delays, lines, and lost directions.
 Instead, take care of local affairs.
 Patience and a sense of humor are needed.

IN CAPRICORN (Dec 22–Jan 19): Avoid buying, 
selling, or renting real estate un
der Capricorn, the sign that governs property matters. Expect
 problems with paperwork, packing, and movers. Reunite with family or vacation at home.

A Man With a Message

Mercury comes from the Latin word merx, or mercator, which means merchant. Mercury is the name given by the ancient Romans to the Greek mythological god Hermes.

Mercury is depicted as a male figure having winged sandals and a winged hat, indicating the ability to travel quickly. He was the official messenger of the ancient gods and goddesses and, as such, governed communications.

In 1782, Mercury became the first symbol of the United States’ fledgling postal service. Today, he is recognized as an icon of an international floral delivery service as well as the official symbol of the postal service of Greece.

In astrology, all of the planet’s attributes are rooted in ancient Greek and Roman mythology. In that context, Mercury is the god of travelers, literature, poetry, merchants, and thieves. He is cunning and clever and witty at a moment’s notice. But he is also recognized as a trickster and thief, prone to misbehavior.

Lipo during mecury rx

Lady Libra here! I have a lipo and fat transfer procedure scheduled 11/6 ... With Mercury Rx, how bad can this be?

Starting An Online Business

During Mercury Retrograde, I'm wondering if I should postpone starting an online store (no contracts, etc. - just listing products to sell).

Education start date during Mercury Retrogade

I am scheduled to start schooling for a new profession. I just realized it will begin during Mercury Retrogade August 6 2018.

Do I delay beginning classes?

Thank you

The Last Sign was Taurus

Llewellyn has a book called Llewellyn’s 2018 Daily Planetary Guide. According to it, the last sign Mercury was in, is Taurus. Fortunately, we have the Almanac to tell us what that means, so that between the two, we can get a better idea of what’s happening. Good luck!


I have a question. What exactly does it mean by what sign the planet is in when it goes retrograde? I am not sure if I am interpreting that correctly. For example, the first Mercury Retrograde for 2018 is listed as March 23 thru April 15. The zodiac sign that covers those dates is Aries. So then Aries would be the sign that Mercury is in when it retrogrades the first time in 2018? If that is correct, then I would also like to know about the third time it goes retrograde which is November 17 thru December 6 which means it would be in two signs during that time frame (Scorpio and Sagittarius). Is that correct? Thank you!

Mercury signs

The Editors's picture

I am not an astrologer, but if I understand things correctly, in western astrology, the signs refer to 30-degree segments along the ecliptic (Sun’s apparent path across the sky over the year at the same time each day). These increments originally referred to the constellations present at that location many years ago. But due to Earth’s slowly wobbling axis, the 30-degree increments no longer exactly align with the constellations; the segments still retain the original names, however. I believe that a planet’s sign refers to the location in relation to the ecliptic.

The dates listed in parentheses in the article above next to a sign are the sign that the Sun is in, not Mercury. We will revise the page so that this is clear–sorry for the confusion! I checked an ephemeris, and, if I am interpreting it correctly, it seems to agree with your data. However, the sign that Mercury is in won’t always agree with the sign that the Sun is in. You’d need to check an ephemeris each year for the particular planet that you are interested in. Mercury will be in the sign of Aries during March 23 through April 15 (actually, early March through mid May). Mercury will be in Scorpio from about mid October through the end of that month, then it goes into Sagittarius for November, then (due to retrograde motion that started in November) back into Scorpio in early December before going back into Sagittarius in mid December after it resumes direct motion. So from November 17 through about December 1, it is in Sagittarius, then goes to Scorpio around December 2, then back into Sagittarius around Dec 13 through the rest of the month. Hope this helps!


I started paperwork to get an equity loan before retrograde but am afraid to turn it in but they're waiting for it they said I was already approved what should I do

Waiting for refinance

No need to wait if things had already been decided before Mercury went retrograde. You are good to go at this point. Just make sure nothing gets lost in the mail if the postal service is to be used. Get tracking if sent by mail and watch it closely.

Will we get back together?

My boyfriend broke up with me at the beginning of the mercury was really odd because we were happy and fine the day before. I read that people who usually break up during the retrograde usually get back when it goes direct. Do you think there's a chance will get back together after this retrograde?

dec. 3 retrograde

ok, since mercury is going retrograde dec. 3, 2017, I would read the Sagittarius one, correct? my friend and I are not on the same page for this. she says I should read MY sign. thank you for clearing this up.

CANCER & LEO dates incorrect

I would try to re do the dates for cancer and leos. July 23 is first day of leo's not the 24th. I love your website and it's accurate but I wouldnt want to show others this website with minor mistakes. Keep up the great work!

Signs and dates

The date that the sun changes sign may vary from time to time . This variance is due to the earth's rotation around the sun. Look up the reason why we have leap year and that may help. For further reference, look at an ephemeris. :)

Zodiac signs

I don't seem to find Dec. 21st.

Mercury retrograde.

When the Merc is in retrograde, take extra precautions everywhere. From your language, actions and communications, to getting enough rest, eating right, and taking a general safeguard with everything. Better to be safe versus sorry. You don't have to win every race, but if you finish, you're in! :)


Hey, I was just wondering what you meant by "You don't have to win every race, but if you finish, You're in!" thank you, what should i be doing during this transformation?


Thank you for this useful, clear information. I love Mercury. Great Guy!! :-)

What if....

What if a large automobile purchase was made during retrograde. It's true indeed the problems that can arise, and have risen with this purchase. What's done is done, but is there anything I can do to put an end to all the issues? I will definitely pay closer attention to astrology in the future.

I made the same mistake, and

I made the same mistake, and I can tell you from experience that selling, trading in, or otherwise ridding yourself of the vehicle is in the best interest of all involved. I did none of the above and after pouring money into the vehicle for years, its engine blew. Leaving my family and I without a car for over a year. Dont do anything during a retrograde other than rest review relax, etc and get rid of that car as soon as you can, but definitely not during another retrograde or you will bring more trouble, wait and when mercury goes direct, I wait a few more days after to be sure, then sell or trade or whatever you have to do, don't wait until it's too late

Selling your home

If you live in Dallas, TX, it is a great time to sell your home. It is a seller's market and people are getting top dollar for real estate. The ones buying are PAYING top dollar. The market in your area has more impact on the answer to your question than do the stars.
