Mercury retrograde
There are three of these windows a year, and each one attracts more legend than fact. Here you'll find the exact dates, the shadow periods, and what actually matters about them.
The next Mercury retrograde
This much is left until the station. It begins on October 24, 2026.
Mercury retrograde
Communication, agreements, travel, technology
Mercury never actually turns around. Earth orbits the Sun faster, and as we overtake Mercury the planet appears to drift backwards against the stars for a few weeks — exactly the way a slower car beside you seems to roll backwards. It is a question of viewpoint, not a cosmic accident.
Astrology reads that apparent backward motion as a turn inward. Mercury governs the way we exchange information: sentences, emails, contracts, timetables. While it retrogrades those processes don't stop, they simply run slower and with more asking again. What people call "chaos" is usually just this: you have to say the same thing twice, and it turns out the first version was less clear than you thought.
Worth doing
- Revisit what was left unfinished — the half-written text, the conversation left open, comes back within reach now.
- Confirm in writing whatever you agreed verbally.
- Build slack into travel plans and deadlines.
- Save and back up anything you would hate to lose.
- If someone returns to your life, hear them out — but leave the decision until after the window.
Better avoided
- Don't sign anything unread, however much you are being rushed.
- Don't launch an announcement or campaign where first impressions decide everything.
- Don't jump to conclusions — ask again before you answer.
- Don't postpone the important conversation until "it's over" — just prepare for it more carefully.
- Don't commit to a big purchase when you're tired, late at night, on a single quote.
The shadow period
The window doesn't begin on the turning day. Mercury first travels across the arc of sky it will later retrace — that is the pre-shadow, roughly two weeks before the station. The themes you will revisit during the retrograde tend to surface here. The post-shadow runs about as long after the end: the planet passes its starting degree again, and the loose ends usually close then.
What people get wrong about it
Mercury retrograde is not a list of prohibitions. You can sign a contract, board a plane, buy a phone — there are three such windows a year, more than two months in total, and life does not pause for them. The difference is care: read the fine print, confirm verbal agreements in writing, and leave half an hour of slack in your schedule. All of that is good practice anyway; the retrograde only reminds you of it.
The next retrograde windows
The dates are computed from ephemeris data, so they don't go stale. The shadow column shows how long the theme runs beyond the calendar window.

Where does it reach you in your own chart?
The same retrograde finds everyone in a different area of life: it depends which house it falls in and which of your planets it sits beside in your birth chart. A general calendar can't tell you that — your own chart can.

These two are far rarer than Mercury's, but longer and deeper. Worth knowing about, because it's easy to blame Mercury for something that isn't its doing.
Venus retrograde
Relationships, money, worth, taste
Venus retrogrades rarely: roughly once every eighteen months, and then for six weeks. It is the slowest and most personal of the three windows, which is why it registers more deeply than Mercury's.
Venus is about what we hold valuable — in people, in things, and in ourselves. While it retrogrades that measure comes up for review. Old relationships reappear, old grievances resurface, and it often turns out that what we missed was something we were waiting for from ourselves. It is not a season of breakups or reunions, but of one question: what is this actually worth to you?
Worth doing
- Look honestly at what you spend on and what you get back for it.
- Reach out to the relationship you've been neglecting — no drama, just a message.
- Settle shared finances before they turn into tension.
- Give yourself time: a realisation that arrives now still holds after the window.
- Let go of what has only been with you out of habit.
Better avoided
- Don't make a drastic change to your appearance that is hard to undo.
- Don't try to resolve in one evening what took years to form.
- Don't buy something expensive purely because it would feel good right now.
- Don't message someone at 3am you haven't spoken to in years.
- Don't read someone's return as a sign — at most, as a question.
The shadow period
Venus has a shadow period too, only a longer one: it opens about five weeks before the station and closes about five weeks after the end. Relationship and money themes therefore open well before the calendar date, and settle later than the official finish.
What people get wrong about it
It is not true that you are "forbidden to fall in love" or to marry under a Venus retrograde. What is genuinely typical: relationships that begin now unfold at a different pace, and the realisations often only come together after the window. A larger purchase — jewellery, furniture, a new look — isn't forbidden either; you are simply more likely to change your mind about it later.
Mars retrograde
Action, momentum, anger, stamina
Mars retrogrades least often of the three: about once every two and a half years, and then at length, for two to three months. Because of that it isn't felt as a daily annoyance so much as the mood of a longer stretch.
Mars is the planet of doing: will, drive, and open anger. While it retrogrades the drive doesn't disappear, it simply stops pointing outward. Things already underway move slower, and conflicts settle in as tension rather than breaking into clean confrontation. This is the season where "why am I doing this?" is a more useful question than speeding up.
Worth doing
- Finish what you abandoned earlier — you have the most patience for it now.
- Build stamina rather than explosive effort.
- Look at what triggers your anger instead of suppressing it.
- Plan: a finished plan can launch the moment the window closes.
- Move your body regularly — Mars energy has to go somewhere.
Better avoided
- Don't provoke a conflict over something that can wait.
- Don't push through exhaustion when your body asks you to slow down.
- Don't decide anything in your angriest moment.
- Don't start something that would need immediate, rapid success.
- Don't take it personally that everything moves harder right now.
The shadow period
Mars has the longest shadow: it opens weeks before the station and runs for months after the end, until the planet regains its starting degree. What stalled during the retrograde usually doesn't restart on the closing day, but when Mars passes that point again.
What people get wrong about it
It isn't that you must start nothing. A Mars window is too long to wait out without losing a quarter of a year. The realistic version: raw force returns less than persistence right now, and in a conflict patience is worth more than speed.
Frequently asked questions
When is the next Mercury retrograde?
There are three windows a year, each lasting about three weeks. The exact days are in the table above: they're computed from planetary positions, so this page won't go out of date in the coming years.
Does Mercury really move backwards?
No. Earth orbits the Sun faster, and as we overtake Mercury the planet appears to drift backwards against the stars for a few weeks — the same illusion as a slower car beside you seeming to roll backwards. The orbit itself doesn't change.
Can I sign a contract or board a plane during one?
Yes. These windows add up to more than two months a year; life doesn't pause for them. What practice does support: read the fine print, confirm verbal agreements in writing, and leave slack in your schedule.
What is the shadow period?
It's the stretch while the planet travels the arc of sky it will retrace during the retrograde. The pre-shadow opens roughly two weeks before the station and the post-shadow closes about the same distance after the end — which is why you often feel it before the calendar says it has begun.
