In short
In astrological tradition, two Scorpios are a union of the water element and the fixed cross: both hold on to what’s theirs, get deeply attached and forgive slowly, which is why trust and jealousy are named as the couple’s main theme. Data from the 2001 census of England and Wales (more than 10 million married couples) did not show that people of the same Sun sign marry each other more often than chance. The Moon, Venus and Ascendant of two Scorpios can be in different signs, so compatibility is calculated from two full dates of birth.
What is known for certain: elements, crosses, rulers
| Scorpio | Scorpio | |
|---|---|---|
| Element | Water | Water |
| Cross (quality) | Fixed | Fixed |
| Ruler | Pluto (classical — Mars) | Pluto (classical — Mars) |
These are definitions of astrology, not a conclusion about the couple: they are the same in all schools.
The Sun passes through Scorpio from October 23–24 to November 21–23; the exact day of the sign change varies from year to year. From October 25 to November 20 the Sun sign is Scorpio in any year of birth, while those born at the edges of this period should check their chart by date and hour.
How tradition reads two Scorpios
Astrologers call the same sign in two people a conjunction: the partners are alike, but don’t make up for what the other lacks. In this reading the water element stands for feelings that are lived deeply and not for show, the fixed cross for persistence and reluctance to change what has once been chosen. The sign has two rulers: Mars in the classical scheme, with Pluto added in the modern one.
From this combination astrologers derive the couple’s plot: both take a long time to look closely before opening up, and once open, they expect complete loyalty and handle unspoken things badly. If a quarrel does happen, neither hurries to give in, and the grudge lasts for weeks. This is a retelling of popular descriptions, not a conclusion from observations — below are ways to check it on yourself.
What researchers found
In 2007, sociologist David Voas of the University of Manchester took the birth dates of husbands and wives from the 2001 census of England and Wales — more than ten million couples. There was a slight excess of marriages within one sign, but Voas linked it to mistakes in filling in dates on the forms; after this correction there were as many same-sign couples as random choice would produce.
It matters what this study did not cover: only Sun signs were compared. The positions of the spouses’ Moon, Venus or Ascendant were not calculated from the census. So Voas’s work leads to a narrow conclusion — the Sun sign alone does not determine who marries whom — not a refutation of astrology as a whole.
What the Sun sign won’t tell you about a couple
The Moon goes around the whole zodiac in a month and stays in one sign for about two and a half days, so for two Scorpios it can be anywhere. Venus moves no further than 47° from the Sun, and for a Scorpio it can be in Virgo, Libra, Scorpio, Sagittarius or Capricorn. Mercury stays within 28° of the Sun — for a Scorpio that’s Libra, Scorpio or Sagittarius.
Synastry, that is, comparing two charts, relies exactly on these points. A Scorpio with Venus in Virgo and a Scorpio with Venus in Sagittarius are different partners to an astrologer, even though a magazine horoscope treats them the same.
How to calculate your couple
The couple calculation on My Seven Charts (svoya-karta.ru) takes two dates of birth and compares them in four systems: natal chart aspects, Human Design, Jyotish kuta points and numerology. The main result is free; with the hour and city of birth it is more precise, but it works without them too.
How to check it on yourself
Check it on your own couple — write down your answer before you look at the calculation.
Take five couples you know where both partners are Scorpios (or your own, if you’re both Scorpios), and five other couples from the same circle.
What should match. If the traditional description is true, in at least 3 out of 5 couples of two Scorpios a grudge after a quarrel lasts longer than a week and there was at least one big argument over jealousy in the past year, while among the other couples this is the case in no more than two out of five. Ten couples is a pointer, not statistics.
When it’s not about you. If couples of two Scorpios have no more lasting grudges and jealous arguments than the rest, the description by sign doesn’t fit your circle — just as in the check of 10 million marriages.
Make sure Scorpio is really your Sun sign: open your natal chart and see which sign the Sun is in.
What should match. With a birthday from October 25 to November 20, the Sun is in Scorpio in any year.
When it’s not about you. If your birthday is October 23–24 or November 21–23, the Sun may have been in Libra or Sagittarius — the exact date, hour and place decide, not a table of dates.
Calculate the couple from two dates and see which signs both partners’ Moons are in.
What should match. By tradition, the “long memory for grudges” shows more strongly when both Moons are in fixed signs — Taurus, Leo, Scorpio or Aquarius.
When it’s not about you. If both Moons are in mutable signs (Gemini, Virgo, Sagittarius, Pisces), and you still don’t manage to make up after a quarrel sooner than a week, the Moons don’t explain it — and neither does the shared Sun sign.
Find Venus in both charts of the couple and write down its element; do the same for five couples you know.
What should match. Astrologers believe that with Venuses of one element (say, one in Virgo and the other in Capricorn — both earth) a couple argues less about how to spend the weekend: if so, couples with Venuses of one element have such arguments less than once a month, and couples with Venuses of different elements more often.
When it’s not about you. If couples with Venuses of one element argue about weekends as much as or more than the rest, this rule doesn’t fit your circle.

Frequently asked questions
Are Scorpio and Scorpio compatible in love?
In astrological tradition — yes, it’s a couple of strong mutual attachment, but with a risk of jealousy and lasting grudges. The census of England and Wales with ten million marriages did not show that the Sun sign affects the choice of spouse, so conclusions are better built on the full charts of both.
Why are two Scorpios jealous of each other?
That’s how tradition explains it: a water sign feels deeply, the fixed cross holds on to what’s its own, and together this reads as a need for complete loyalty. It’s a description, not a law — if there’s no more jealousy in your couple than in those you know, it doesn’t apply to you.
How do I find out the compatibility of two Scorpios by date of birth?
You can enter both dates in the couple calculation on My Seven Charts (mysevencharts.com/compatibility/): it compares natal charts, Human Design, Jyotish and numerology, and shows the main summary for free.
What sign is my Venus in if I’m a Scorpio?
Venus is never further than 47° from the Sun, so for a Scorpio it’s in Virgo, Libra, Scorpio, Sagittarius or Capricorn. The exact sign is shown by the natal chart from your date of birth.
Can a couple of two Scorpios be calm?
It can: the Sun sign is only one point of the chart, and the partners’ Moon, Venus and Ascendant can be in completely different signs. If your quarrels are rare and quickly forgotten, the traditional description simply isn’t about your couple.
