Mercury’s last period of retrograde motion in 2021 lasts from September 27 to October 17! According to the age-old practice of astrology, we are all influenced by the effect of Mercury in retrograde. What exactly does it mean for each of us, though? Read on to find out.

What Is “Mercury Retrograde”?

Three times a year, the planet Mercury appears to travel backward across the sky. We refer to these periods as times when Mercury is in apparent retrograde motion, or simply ”Mercury retrograde.” To those who practice astrology, these times in particular were traditionally associated with confusion, delay, and frustration. Think undelivered love letters, email blunders, and frazzled travel plans! This is an excellent time to reflect on the past, however, and it’s said that intuition is high during these periods. Coincidences can be extraordinary.

What Is Retrograde Motion?

The astronomical explanation for retrograde motion starts with understanding that the planets in our solar system orbit the Sun at different distances and speeds. While we orbit the Sun ourselves, we can observe the other planets moving across our sky, following their own paths. 

Sometimes, it can appear (from our perspective) that a planet has abruptly switched directions and has started to move in reverse across the sky. This is, of course, an illusion caused by the position of Earth in relation to that of the planet, since a planet in orbit always travels in one set direction and can’t suddenly reverse course. This is why we call the phenomenon apparent retrograde motion, as it only looks like the planet is moving backward (“retrograde motion”)!

When Is Mercury in Retrograde in 2021?

In 2021, Mercury will be in apparent retrograde motion during the folowing ranges of dates: 

  • January 30 to February 20 
  • May 29 to June 22
  • September 27 to October 17

Please note that dates reflect Eastern Time U.S., not Universal Time.

What You Should Do When Mercury is Retrograde

The planet Mercury rules communication in all forms—listening, writing, reading, speaking, and so on—as well as activities closely related to communication, like negotiations and contracts. It also rules travel, automobiles, shipping, and mail.

So, when Mercury is retrograde, try to remain flexible, patient, and understanding, allow extra time for travel, and avoid signing onto any new contracts that you’re unsure of. Double check your email responses and check in with reservations before you take that trip. 

Review projects and plans at these times, but wait until Mercury is direct again to make any final decisions. You can’t stop your life, but plan ahead, have back-up plans, and be prepared for people’s shorter fuses and miscommunication. 

Take a Moment to Reflect

Some blame Mercury retrograde for all chaos that happens in their lives. However, this is a good time to sit back and review what you put your energy toward.

For example, if family and faith are important to you, are you putting enough of your energy into them or have you become overextended in other areas such as your career or a hobby? Losing the balance between different parts of your life can cause all of them to suffer, so being aware of the connections between them—especially during Mercury retrograde—can help you to maintain or at least better understand how that balance works.

Take a moment to reflect. Mercury retrograde can be an excellent time to take a step back and reanalyze who you are and what you are doing—but do refrain from making any drastic changes until after retrograde has ended.

Mercury and the Zodiac

The type of influence you feel also depends on which of the 12 zodiac signs Earth is in when Mercury goes retrograde.

Lisa, you got a loser! He

Lisa, you got a loser! He crawls back to you because he knows he can! Wake up! He's robbing you of your self respect. Throw the bum out! It's worse for your child seeing this going on!
Once a cheater, always a cheater! They don't change! Give your child a stable home and get rid of him.

MR is the least of your

MR is the least of your problems. Your choice in men is bad. Grow a spine & kick this jerk to the curb! We teach people how to treat us.

Dear love, no one can tell

Dear love, no one can tell you how to follow your heart except to follow your heart. Your inner self will tell you the right thing to do. You may want to seek guidance from a counselor about this. One thing for sure, when we give our bodies to a man who does not respect us, we lose self respect too. Cheating is not necessarily the end, but in my experience, sharing a man typically gives him carte blanche to continue to play around.

Wow, my boyfriend and I

Wow, my boyfriend and I almost broke up March 6-10, then again June 24-29. Both during Mercury retrograde or darn close to it.

He broke up with me last weekend, a week before Mercury goes retrograde again. He called yesterday wanting to work it out...But Mercury is about to go into retrograde again tomorrow!

He has Gemini moon and a number of planets in Virgo. I have a Virgo sun.

What to do?!? I don't want to lose him...

Mercury retrograde usually

Mercury retrograde usually means miscommunication, lost data, lost car keys, etc. I would say that the realizations about your relationship have more to do with Mars, Venus, and the Lunar Eclipses and New Moons that have happened lately.

I was born when mercury was

I was born when mercury was in retrograde. As a result my bad luck happens within the week before MR. But during MR, I can't do anything wrong. My business thrives, my relationships are remedied or end because they should. MR is the best time for me. I look forward to them. I am a Scorpio with an Aries ascendant. All of he posts regarding dating, breakups, buying, and signing. If you are truly interested in making decisions regarding MR or any other transitions, you should plan better. Do not forget the other person is affected differently by the transits. You need to check their signs and their issues, to help you solve yours. But mostly, you should step forward in life and stop trying to step backwards.

Any bad intentions by the

Any bad intentions by the offeror of the contract should be just as defective during MR as any bad intentions you may have. Make life happen. Just plan better.

I am in the process if

I am in the process if interviewing for a job that I used to do before just at a different company. Will this situation work in an MR? Same area, similar title, same responsibilities but different company and product.

This is my first time to hear

This is my first time to hear MR its sounds interesting I'm a Scorpio lady and my bf is a Married Cancer guy does this Mr has a good effect to our relationship? I mean does our relationship will be more stronger? I was born on October 30,1972.He was born on July 16,1969. How this MR affect our relationship? I hope it could answered I love him.

Scorpio and Cancer are of the

Scorpio and Cancer are of the same element (water), which by itself, means little. All of it depends on other planets in your respective charts, how those planets are related to each other and how your current transits are affected.

If you know the time of your respective births, you can check out (you'll also need to input your birth locations).

Planets that govern these types of relationships are the moon, Venus and Mars.

It's a place to start.

OMG only a scorpio sex addict

OMG only a scorpio sex addict would have the nerve to come on asking for advice in adultery with a married cancer... Your relationship success in whole is already doomed. Move on to someone more appropriate.

Be careful how you judge.

Be careful how you judge. It's doubtful that you have all of the information and those that are 'superior' are quite frequently the next to fall. Consider this your warning....

Firstly he's MARRIED!!! Love

Firstly he's MARRIED!!! Love him all you want but he's using you. MR has nothing to go with your stupidity. Dont play second fiddle to a man who took vows. Why do women steal other women's men, fall in love and then the men use it as leverage in using you. And hurting another person or family.

Um, my grandmother

Um, my grandmother gave me this advise long ago.
If he will cheat with you, he will cheat on you. What makes you so special that you would change the nature of a man ?

Cancer men often cheat and

Cancer men often cheat and NEVER leave their wives.

It took me sooo long to get

It took me sooo long to get on the blush bandwagon, too, Tricia!

I have met a guy during MR.

I have met a guy during MR. At the time I was not interested, but after the date changed my mind, but it was too late. He replied that he wasn't interested. I can't stop thinking about him. Can he change his mind if he made that decision during MR? Should I contact him again when Mercury is retrogate (as it brings people from the past) or should I contact him when Mercury is direct, so there is no further problem in communication. Meeting him during MR was the worst timing ever, we didn't communicate very well... And it left a bad impression. Or should I just forget about him and move on?

The meeting chart steers the

The meeting chart steers the relationship. If this is meant to be you can look at the natal synastry, I don't put everything based on a simple mercury retrograde there are many more complicated factors.

If he's not interested, not

If he's not interested, not much any planetary influences can do about this. Find someone who IS interested! If the synastry is good it's good. It's obviously not good if he's not interested. Allow a universe-arranged relationship.

I broke uo with my ex-gf 3

I broke uo with my ex-gf 3 months ago for the 2nd time. I realize I made a mistake both times. I attempted to reconcile during the first day of retrograde 6/26. She didn't want to. We were together for over a year & thought we were soul mates. There was even akashik record stuff on both ends, separately before we got together. There's a lot more to this. Anyway, she said she's not dating & neither am I while we both work on ourselves. She said that she doesn't think she wants to reconcile ever in the future but she said she's not completely sure. Is there a chance for us to reconcile when I'm done working on myself (in 4-6 months or so)? I'm recently divorced 2 months ago.

A lot of problems with

A lot of problems with Mercury in retro are misattributed. That tiny mud ball has very little influence on human beings. And while in retro, intuition is high during these periods, and coincidences can be extraordinary.
No, solar flares are the current issue and geomagnetic interference caused by these unpredictable flares. I am afraid there is at least another year before things settle down. Be patient.

Hey Tim , If you only

Hey Tim , If you only divorced 2 mos. ago? I'd say you still have alot of issues to work out. Divorce is like death and many of us tend to cling to others to help us over the hurdles of a break up. No matter how much you and your ex-wife may have agreed it was best. I would say give yourself at least a full year before you plan to be serious with someone else. You don't want them to feel the residue of your past relationship. You're already bringing in someone and breaking up with them..that is totally unacceptable and just because the 2 of you feel a spiritual connection, doesn't mean you should be in a committed relationship. I have a soul mate and even though we thought of being each others loves, we knew our friendship and bond was more important than the intimacy that involves sex and family. Just let her be and not confuse her. Also you don't know that 4-6 mos of working on yourself is enough time. If you need companionship then have dates and be platonic. Learn to be someones friend first and not think only of your needs to have someone by your side.

Thats so sad. I hope you can

Thats so sad. I hope you can work it out. Because true love is had to come by. I know this awesome Spiritual Advisor Scarlet. She really help me with my situation.If your into that type of thing here is will tell you this shes so amazing and caring:).You will not regret it!!!!

you divorced 2 months ago and

you divorced 2 months ago and were dating your gf as recently as 3 months ago. astrology has nothing to do with your problems. work on yourself for a few years and stop acting like a fool.

your last sentence needed to

your last sentence needed to be your first. with the emotional upheaval of a divorve, a new realtionship so soon is hardly doable. you may try to justify it in your present state of mind but given yourself a significant emotional rest to regroup and recover. explore other ways for now to disract youself from relationships. spend time with a hobby, travel, visit new places closer to home. D!o volunteer work. There are so many community initiatives that could use a little help. above all, rest your emotions and give your heart a chance to recharge.
