The Three Mercury Retrogrades of 2026

Mercury begins three retrogrades in 2026, in Pisces, Cancer and Scorpio, all water signs. For each one you get the minute it stations retrograde and direct, the degree where it turns, and the dates its shadow begins and ends.

What Happens When Mercury Turns Retrograde

Mercury circles the Sun in 88 days on an orbit inside the Earth's. Each time it laps us it passes between the Earth and the Sun, and for about three weeks around that pass its motion against the background stars reverses. Nothing about the planet changes. The reversal is a matter of sight lines: a planet overtaking us on the inside track looks, from here, as if it were sliding backward.

At each end of the reversal Mercury seems to stand still. In the stations listed on this page it stays within 10 arc-minutes of its turning degree for 2.6 to 4.3 days, the shortest pause of any planet, which is why Mercury's station days pass quickly while Saturn's stretch over weeks.

Astrology gives Mercury the traffic of daily life: speech and writing, numbers and accounts, contracts, trade, errands and short trips. It rules Gemini and Virgo. Retrograde, these matters are read as turning back on themselves. Plans get revised, messages get reread, and business that was set aside returns to be finished.

The familiar advice to avoid signing or launching during these weeks follows electional astrology, the practice of choosing a start time for an undertaking. A retrograde Mercury describes a beginning that will be revisited, so the tradition prefers to start new things after the station direct and to give the retrograde to the work that begins with "re": review, repair, renegotiate, reply.

How Mercury Retrogrades Step Back Through the Elements

Mercury's retrogrades come about 116 days apart, and each begins 105° to 127° further along the zodiac than the last, roughly a third of the circle. Three of them take about 349 days, a little short of a year. That shortfall sets the pattern: each retrograde starts 16 to 20 days earlier in the calendar than the one three before it, and 15.8° to 20.1° further back in the zodiac.

Signs a third of the zodiac apart share an element, so a year's retrograde stations usually fall in one element. That holds in 10 of the 11 years in the grid below: fire in 2025, water in 2026–2027, air in 2028, earth in 2030, fire in 2031–2032, water in 2033 and air in 2034–2035. Read in order, the elements run backward through the zodiac's sequence of fire, earth, air and water, one step every year or two.

2029 is a hand-off year: the stations alternate between air and earth signs as the set crosses from one element into the next.

2029 has four Mercury retrogrades where other years have three: the first stations on January 7, 2029 and the fourth on December 22, 2029, both inside the same calendar year.

Every Mercury Retrograde, 2025 to 2035

All 34 Mercury retrogrades from 2025 to 2035, grouped by the year each one begins. They last 19 to 24 days, 21.7 on average, and 17 of them cross a sign boundary, starting in one sign and backing into the one before. Over the whole span Mercury is retrograde 18.8% of the time, about 69 days a year.

Each station is the minute at which Mercury's speed in longitude passes through zero, found with a high-precision ephemeris. The shadow runs from the first crossing of the direct-station degree to the last crossing of the retrograde-station degree, as set out on the About page. Shadow dates are UTC calendar dates.

Inferior Conjunction, and the Transit of 2032

Partway through each retrograde Mercury passes between the Earth and the Sun. In the 34 retrogrades from 2025 to 2035, that inferior conjunction comes 40.7% to 59.2% of the way from one station to the other, with Mercury 0.55 to 0.68 AU away (82 to 101 million km), close to its nearest approach of the cycle. For days on either side it is lost in the Sun's glare, so every Mercury retrograde contains a stretch of combustion.

Usually Mercury slips past a little north or south of the Sun, because its orbit is tilted against the Earth's. When an inferior conjunction falls near one of the two points where the orbits cross, Mercury crosses the face of the Sun instead. In this table that happens once: on November 13, 2032, Mercury's center comes within 9.5′ of the Sun's at 08:54 UTC, inside the solar radius of 16.2′. It is visible only through a properly filtered telescope.

Working With a Mercury Retrograde

Born During a Mercury Retrograde

Mercury is retrograde 18.8% of the time between 2025 and 2035, so roughly one birth in five has it. Charts mark it with an R or ℞ beside the planet.

William Lilly's table of fortitudes and debilities in Christian Astrology (1647) scores a retrograde planet at minus five, one of the heavier accidental debilities. Modern astrologers read it less as a weakness than as a way of working: a mind that reaches conclusions by going back over the material, that writes better on the second draft than the first, and that often understands faster than it speaks.
