Mercury Retrograde in Aries: Every Date and Degree

Every Mercury retrograde in Aries

Mercury turns retrograde three or four times a year for about three weeks each time, and because of how its orbit lines up with ours the retrogrades cluster in one element for a year or two before moving on. These are the periods that start or end in Aries.

The degrees matter more than the dates for anybody with a chart in front of them. A retrograde that stations on a degree close to something of yours is the one you will notice; the rest are weather. Mercury covers the same stretch of zodiac three times during a retrograde, forward, back and forward again, which is where the idea of revisiting comes from and is literally true of the planet.

What retrograde motion actually is

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.

Why Aries changes the flavour

Aries is Fire and Cardinal, ruled by Mars. So a retrograde here tends to land on arguments started faster than they can be finished, and messages sent before they were ready.

That is the whole of what the sign adds. A retrograde in Aries is not worse or better than one anywhere else. It points at a different part of life, and the degrees tell you whether it points at yours.

Which part of your life it lands in

The sign is the same for everybody. The house is not, and the house is what decides whether a retrograde in Aries touches your job, your money or your marriage. On whole sign houses it follows straight from your rising sign.

That is the difference between a horoscope and a reading. The same three weeks are a paperwork problem for one person and a conversation with a partner for another, and which it is for you was fixed by a birth time.

What to actually do with it

1. Use it as a prompt, not a prohibition. Mercury retrograde in Aries is a good three weeks to re-read, revisit and finish things, which is useful advice whether or not the astrology holds.
2. Do not postpone something important on account of it. People have lost jobs and houses waiting for a planet, and no reputable astrologer would advise that.
3. Back things up and read the email before you send it. That is good practice in any three weeks.
4. If you want to test it, write down what happens. Most people who are certain about retrogrades have never kept a record, which is exactly the condition under which bias thrives.

Where to read next

Mercury in Aries as a birth placement is the permanent version, which is a different thing: about one person in eight is born with Mercury retrograde, and for them the whole idea reads rather differently. The 2027 Mercury retrogrades are listed here.
