Mercury retrograde: what it really is and how to live through it calmly

An email sent to the wrong person, a delayed train, a misunderstanding with someone close… and somebody sighs: “It’s Mercury retrograde!” The phrase has gone round social media many times, often with a small dose of anxiety attached. Yet behind this phenomenon lies a beautiful astronomical reality and, in astrology, a rather gentle invitation: slow down, reread, revisit. Let’s take stock, calmly.

What is Mercury retrograde?

An optical illusion seen from Earth

Let’s begin by reassuring the scientific minds: Mercury never goes into reverse. Like all the planets, it always travels around the Sun in the same direction. “Retrograde” describes an apparent motion, in other words what we perceive from our observation point, the Earth, which is itself moving.

Mercury is the planet closest to the Sun. It completes an orbit in about 88 days, compared with 365 for the Earth. Regularly, it “overtakes” our planet on the inside track, passing between the Earth and the Sun. During this overtaking, seen from Earth, Mercury seems to slow down, stand still, then move backwards against the background of the stars, before resuming its usual course.

It is the same impression as when you are on a train overtaking another: for a few moments, the neighbouring train seems to be going backwards, when it is simply moving more slowly than you relative to the landscape. Astronomers in antiquity had already observed these loops in the sky, which puzzled scholars for a long time before being fully explained by the heliocentric model.

How many times a year, and for how long?

Mercury appears retrograde about three times a year, sometimes four in a calendar year, for about three weeks each time. In total, that is nearly a fifth of the year. In other words, it is a perfectly ordinary phenomenon, which comes round regularly and which generations have lived through without mishap.

Astrologers also distinguish the days surrounding the period:

• the retrograde station, the moment when Mercury seems to stop before moving backwards;
• the retrograde phase itself, of about three weeks;
• the direct station, when Mercury seems to stand still again before resuming its normal course;
• the shadow period, from a few days to two weeks before and after, during which Mercury travels through the degrees covered by the loop.

Mercury is not the only retrograde planet

All the planets, apart from the Sun and the Moon, go through phases of apparent retrograde motion. Venus does so about every eighteen months, for around forty days; Mars roughly every two years, for two and a half months. The more distant planets, such as Jupiter or Saturn, even spend nearly four months a year in retrograde motion: for them, it is the faster Earth that overtakes them. If Mercury attracts so much attention, it is mainly because its retrogrades are frequent and its themes, communication and travel, touch our daily lives.

What does Mercury symbolise in astrology?

In the astrological tradition, Mercury is the messenger of the gods. It rules Gemini and Virgo, and it symbolises everything that circulates: words, ideas, exchanges, short journeys, writing, trade and learning. It represents the way we think and communicate.

When it is retrograde, astrology considers that these areas turn inwards. It is not a cosmic “bug”, but a change of pace: Mercury’s energy invites us less to rush ahead than to reflect, less to launch than to polish.

The main themes of Mercury retrograde

Notice how many words begin with “re” when we talk about this period. It is no coincidence: Mercury retrograde is traditionally a time of return.

• Reread: your messages, your contracts, your notes. One more check costs nothing.
• Revisit: a project left on hold, an old idea, a place from the past.
• Reconnect: people you have lost touch with often resurface, and it is a lovely opportunity to pick up the thread.
• Reorganise: sort your files, tidy your desk, update your tools.
• Reflect: take your time before deciding, let a decision ripen.

Seen this way, the period looks less like a zone of turbulence and more like an interlude well suited to introspection and finishing touches.

Taking the drama out: what Mercury retrograde is not

Let’s be clear: Mercury retrograde causes neither disasters nor misfortune. The little hitches of everyday life happen all year round; during these three weeks, we simply tend to notice them more, because they are on our minds. It is a well-known quirk of our attention: we see what we expect to see.

So there is no reason to put your whole life on hold for three weeks. Signing an employment contract, buying a device, moving house, getting married: if the timing is right for you, it is right. At Orbelune, astrology is offered as entertainment and a tool for personal reflection; it never replaces common sense, nor the advice of a professional for important decisions. If Mercury retrograde simply inspires you to read a document twice before signing it, that is an excellent habit, retrograde or not.

Mercury retrograde is not a storm to flee, but a tide gently going out, revealing what deserves your attention.

How to live through Mercury retrograde calmly

In communication

• Take the time to rephrase: “If I understand you correctly, you mean that…”. It works wonders against misunderstandings.
• Reread your important messages before sending them, and check who they are going to.
• Choose face-to-face conversations for delicate subjects.

In organisation

• Back up your files and photos: good practice in any season.
• Allow a little extra time for your journeys, simply for peace of mind.
• Finish current projects before starting new ones, if you can.

In your inner life

• Keep a notebook: jot down the ideas, memories or people that come back to you.
• Give yourself moments of rest, reading and walking, away from screens.
• Ask yourself: what in my life deserves to be looked at again with fresh eyes?

A few questions to ask yourself during the period

1. Which conversation have I left hanging, and do I want to pick it up again?
2. Which old project still makes me dream?
3. Which communication habit would I like to soften?

A period that favours creativity

It is often forgotten, but looking back is a wonderful creative engine. Writers know it well: a text is born in the first draft, but it is the rereading that gives it its shape. Mercury retrograde can be the ideal moment to return to a manuscript, rework a piece of music, complete a sketchbook or take up a language you once learnt. What has been started sometimes deserves a second chance, and the period lends itself to this beautifully, symbolically speaking.

You can also make the most of it to reread your own notebooks, old messages and photos. Looking back at the road travelled often gives a lovely perspective on the one still ahead, and reminds you how much you have already grown.

And according to your sign?

Each retrograde takes place in a sign of the zodiac, and symbolically touches a different area of your chart depending on your rising sign. A retrograde in a Water sign might, for example, invite you to revisit your emotions and family ties; in an Air sign, your ideas and exchanges. To find out which area of your life is concerned, the simplest way is to know your birth chart and follow your personalised horoscope.

In conclusion

Mercury retrograde is a magnificent optical illusion, born of the planets’ dance around the Sun. It comes round about three times a year, for roughly three weeks, and astrology sees it as a time for rereading, returning and reflecting. Nothing more, nothing less: no cause for concern, rather an invitation to slow down.
