Mercury Retrograde


Mercury completes its orbit around the Sun in about 88 days, while Earth takes 365 days.

Since Mercury travels faster, it zooms past Earth 3-4 times each year.

As Mercury "rounds the bend," it appears to slow down, stop, move backward, stop again, then move forward— this cycle is known as retrograde or Rx from the Latin word "retrogradus" meaning "backward step."

Mercury rules:

  • The conscious mind
  • How we perceive and relay information
  • Speaking, listening and negotiating
  • Buying and selling
  • Contracts, mails and other documents
  • Anything that has moving parts
  • Distribution networks
  • Short travels

Q: What happens during Mercury Rx?

Have you ever watched a child coloring a page?  Back and forth...back and forth.

That is what happens when Mercury is retrograde.  We must learn to have presence of mind and be present to what we are doing or Mercury will make us go back and forth until we learn our lesson.

In a nutshell, whenever a Planet turns retrograde, it is time to pay attention to matters ruled by the Planet.


Popular DON'Ts during Mercury Rx: 

  • Do not sign contracts and submit important documents
  • Do not start a project that will take more than a day to complete
  • Do not purchase gadgets, electronics, vehicles and anything with moving parts
  • Do not renew your passport or apply for a visa
  • Do not trust your memory
  • Do not change your PINs and passwords
  • Do not undergo elective surgery
  • Do not get married

Schedules will keep changing, traffic will snarl, and important documents could be misplaced.

For long trips, buy travelers checks, and carry-on important items and a set of clothing.  Do not rely on weather reports; weather patterns can run wild.

DO things that start with "RE":  repair, research, recalculate, rethink rewrite, retake, repossess, recall and remember

  • Mercury Rx jolts us to review and REvise our life
  • Attend to accounting matters (REcount)
  • Look up an estranged lover and REunite
  • Write your account number clearly when you pay a bill
  • Secure your wallet in a vault
  • Put shackles on your day planner
  • Anchor your pen with a ball and chain
  • REpair a vehicle
  • Clean your house
  • REcycle and give away things you no longer need

Your memory will be like burnt toast during Mercury Rx.   Guidelines and requirements will keep changing.   Promises made will be ignored and appointments can be postponed.   These are definitely not the right conditions for doing business.

Start a business after Mercury goes direct.  If you want to play safe, wait until Mercury exits its Post-Shadow period.

VERY IMPORTANT:  Avoid scheduling Mercury-related activities from the time Mercury enters its Pre-Shadow period until Mercury exits its Post-Shadow period.

At the very least, avoid dates when Mercury turns retrograde and goes direct.   To know the exact dates, download this year's Planet Retrograde Calendar.


Q: I really need to sign a contract.  Is there a remedy?

It's hard to put mercurial tasks on hold while Mercury is Rx.  Don't despair.  There is a remedy  only a few know about.  

Rx on a doctor's pad originated from the Latin word "recipere" meaning "to take"

THE REMEDY: Morning or Evening Star

Run a chart for the day you plan to sign the contract to know if Mercury is a morning or evening star or refer to the dates below.

Morning Star.  If Mercury rises and sets before the Sun, it is considered a "morning star."  That means, its good qualities shine from dawn to sunset (DAY), and its undesirable qualities are prominent sunset until dawn (NIGHT).


If you need to sign a contract or do other mercurial tasks, do it before the Sun goes down preferably at the Hour of Mercury.  Avoid timing mercurial activities after sunset especially during the hour of Mercury.

Evening Star.
If Mercury rises and sets after the Sun, it is considered an "evening star."  The opposite will apply:




Sep 10 thru Sep 21   Evening Star, NIGHT GOOD, DAY BAD

Sep 22                      Transition, do not perform Mercurial tasks 

Sep 23 thru Oct 2     Morning Star, DAY GOOD, NIGHT BAD


  • Be mindful of your thoughts and the things you do.
  • When you find yourself going back and forth, take a deep breath to calm down, pull yourself together, and return to your center.
  • From your center, smile and raise your vibe. By doing so, you will be in a better state to deal with the situation.
  • Remember: Things always happen for a reason.
  • Relax and Ask: Why?  Why is this happening?  What can I learn from this?
  • Do a good deed to raise your vibe.

Q: Is Rx a myth?

Observe what happens and journal your experiences so you can determine if there are substantial RE's during Rx periods.


Why am I experiencing things going back and forth even before Mercury turns Rx?
