Astrology CalendarMercury Retrograde 2027: The Exact Dates
Three windows in 2027, with stations to the minute and the degrees each one covers. Computed from an ephemeris, not copied, and dated so you can tell.
Retrogrades
Uranus goes retrograde once a year, for about five months, read as a review of change, disruption and the thing you want to break out of. The computed dates, what retrograde motion physically is, and an honest account of the evidence.

Computed from the ephemeris: these are the moments Uranus's apparent motion changes direction, which is the actual definition of a station rather than an approximation of one.

To the hour: Uranus turned retrograde September 10, 2026, 2:40 PM ET and goes direct February 8, 2027, 7:22 AM ET.
No planet goes backwards. Retrograde is an appearance, and it is the appearance that gave astronomy one of its hardest problems for two thousand years. A planet looks like it reverses because we are watching it from another moving planet: when the Earth overtakes an outer planet on the inside of its orbit, or an inner planet overtakes us, the line of sight swings the other way for a while.
The same thing happens on a motorway. Overtake a slower car and, against the distant hills, it appears to slide backwards for a few seconds. Nothing about the other car changed. Your position did.
Explaining those loops is what Ptolemy's epicycles were for, and getting rid of them is a large part of why heliocentric astronomy won. So retrograde motion is completely real, completely understood, and entirely a matter of where you are standing.
Uranus retrograde is traditionally read as a review of change, disruption and the thing you want to break out of. The reasoning is straightforward once you know what the motion is: the planet covers the same stretch of zodiac three times, forward, back, and forward again, so anything it touches gets touched three times. Revisiting is a description of the geometry before it is an interpretation.
Uranus is retrograde about 41 per cent of the time. That figure is worth knowing, because the amount of attention a retrograde gets is almost exactly inverse to how rare it is. Mercury retrograde is famous and common. Venus retrograde is uncommon and barely discussed.
| Planet | Retrograde | How often |
|---|---|---|
| Mercury | about 19% | 3 or 4 times a year, 3 weeks each |
| Venus | about 7% | every 18 months, about 6 weeks |
| Mars | about 9% | every 2 years, 2 to 3 months |
| Jupiter | about 30% | yearly, about 4 months |
| Saturn | about 36% | yearly, about 4 and a half months |
| Uranus | about 41% | yearly, about 5 months |
| Neptune | about 43% | yearly, about 5 months |
| Pluto | about 44% | yearly, about 5 and a half months |
The outer planets are retrograde for so much of the year that treating one as an event makes little sense. What astrologers watch there is the station: the few days the planet appears to stand still before turning, which is when it is moving slowest against the sky and sitting longest on one degree.
Uranus is retrograde about 41 per cent of the time, so a meaningful share of people have Uranus retrograde in their birth chart. The usual reading is that the planet's job gets done inwardly or on a second pass rather than straightforwardly, which is a description rather than a problem. It is not a flaw, it is not rare enough to be special, and a chart with it is not worse than one without.
Whether yours is retrograde needs the chart calculated, although for this one a birth time is less critical than usual: retrograde status does not change through a day.
September 10, 2026 to February 8, 2027, which means it is retrograde now. The table on this page lists the next ten periods.
Once a year, for about five months.
It is read as a review of change, disruption and the thing you want to break out of.
No. It is an optical effect of watching one moving planet from another moving planet. The same thing makes a slower car appear to slide backwards as you overtake it.
