My dear, few phrases in modern astrology cause quite so much fluttering as Mercury retrograde. The trains run late, the email vanishes, the old flame telephones out of a clear blue sky, and somewhere, someone sighs knowingly and blames the little planet nearest the sun. Three or four times a year, for about three weeks at a time, Mercury acquires a reputation somewhere between a burst pipe and a family curse.

I should like, from my quiet writing desk in Bath, to restore a little dignity to the proceedings, because the truth about Mercury retrograde is far more interesting than the panic, and considerably more useful. Properly understood, these weeks are not a curse at all. They are the heavens’ quarterly review period, and the women who learn to use them come out ahead of those who merely brace and endure. Let me explain.

What Does Mercury Retrograde Mean?

Mercury retrograde is the period, roughly three weeks, occurring three or occasionally four times a year, when Mercury appears, from our vantage on earth, to move backwards through the zodiac.

Note the word appears. No planet truly reverses course. The effect is an optical one, exactly like the moment a swift train passes a slower one and the slower seems, for a strange minute, to glide backwards. Mercury orbits the sun in 88 days to our 365; several times a year our two carriages pass, and from our window Mercury seems to retreat across the sky. The ancients, who watched with great care, noticed that these apparent retreats coincided with a particular weather in human affairs, and it is that weather we speak of when we speak of retrograde.

In astrology, Mercury governs communication, information and movement: letters and contracts, conversation and negotiation, travel and errands, and all machinery of message-carrying, which in our day means the telephone, the computer and the inbox. When Mercury turns retrograde, this whole department of life turns inward and backward. Matters stall, return, repeat and revise. The prefix tells you everything, my dear: re-. Review, revise, reconsider, reconnect, repair, rest.

Why Does Everything Go Wrong During Mercury Retrograde?

Here is my honest answer: it doesn’t, but our forward motion goes wrong, because the season is not built for forward motion. Trying to launch, sign, and dash about during a retrograde is rather like doing spring cleaning during a dinner party: the fault lies not in the house but in the timing.

The classic retrograde weather is real enough, and you will recognise it. Messages miscarry, the email misunderstood, the text sent to the wrong person, the crossed wires between old friends. Plans revise themselves, the delayed train, the postponed meeting, the appointment moved twice. Machinery grows temperamental. Papers and contracts reveal their fine print at inconvenient moments. And, most famously, the past returns. Old friends, old colleagues, old lovers: retrograde is the season of the returning figure, of unfinished conversations circling back for completion.

None of this is punishment. Mercury retrograde is the heavens pressing a quarterly pause: before you rush on, look back. Something behind you wants finishing.

What Not to Do During Mercury Retrograde

The traditional cautions, which I pass on with my own annotations. Where possible, avoid signing major contracts or making large purchases, not because doom attends them, but because retrograde specialises in hidden details and second thoughts; if you must sign, read everything twice and keep copies. Avoid launching the great venture, the business, the announcement, if the date can decently wait three weeks. Be slow to take offence: assume the muddled message was muddle, not malice, and you will spare yourself half the season’s quarrels. And back up the computer, allow extra time for journeys, and confirm the appointment before setting out. Simple seamanship, my dear.

What Mercury Retrograde Is Actually For

Now to the part the panic merchants never tell you. Every re- forbidden to forward motion is favoured in reverse. Retrograde is the finest season of the year for: reviewing, the project, the finances, the drawer of unanswered letters; revising, the manuscript, the will, the plan that never quite worked; reconnecting, this is the classic time old friends resurface, and the season smiles on reunions sincerely meant; repairing, the leaking tap, the strained friendship, the neglected correspondence; and resting and reflecting, for Mercury retrograde is, above all, contemplative weather, when intuition speaks unusually clearly through the pause.

I keep a small retrograde custom myself and commend it to you: at the start of each retrograde, I ask, “What have I left unfinished that this season wishes me to complete?” One answers surprisingly quickly. Then I spend the three weeks finishing it. Women who use retrogrades this way stop dreading them entirely, and find, three or four times a year, that the heavens have handed them a tidy season expressly for putting their house in order.

What About Old Lovers Returning?

I must address this, because it is the retrograde question I am asked most often, usually in a letter that begins “Madame Grace, you will never guess who wrote to me.” Yes, retrograde famously restores old flames. And no, his return is not automatically a sign from the stars that he is your destiny. Retrograde returns the past for completion, and completion takes two forms: sometimes rekindling, when the parting was a matter of timing rather than truth; more often, a final understanding, the apology, the explanation, the closing of a door left swinging for years, so your heart may stop listening for it. Ask yourself honestly which is on offer before you answer that letter. And if you cannot tell, my dear, that is precisely the sort of question a personal reading exists to answer.

Frequently Asked Questions

How long does Mercury retrograde last? About three weeks, three to four times each year, with a few days of “shadow” on either side as the effect gathers and disperses. Dates for each year are published in every almanac, and I always give them in my letters.

Should I really not sign anything during Mercury retrograde? Life cannot always wait on the sky, and the stars incline, they never compel. Sign if you must; simply read twice, question the fine print, and keep copies. The caution is about attention, not doom.

Does Mercury retrograde affect relationships? Chiefly through miscommunication and the return of the past. Grant your loved ones the benefit of the doubt in muddled exchanges, and treat returning figures as unfinished chapters, some to be rewritten, most to be gracefully closed.

Is anything good about Mercury retrograde? A great deal, as I hope I have shown. It is the sky’s review season: unmatched for revising, reconnecting, repairing and finishing. The wise do not endure retrogrades; they use them.

A Word Before the Next Retrograde

There is always another retrograde on the calendar, my dear, and there is no reason it should catch you unprepared. I write regularly to my circle of readers from Bath with the celestial weather ahead: retrograde dates and what each one asks, the moons and their moods, and a word from the oracle and the angels.
