A Juno sign calculator finds the zodiac sign and house of the asteroid Juno at your birth, which astrologers read as the qualities you need in a committed partner and the way you approach marriage and long-term loyalty. Where Venus shows who you are attracted to, Juno shows who you want to build a life with. Because Juno moves faster than the outer planets and can change sign every few weeks to months, you need your full birth date, and ideally your time and place for the house.
This guide covers what Juno means, how to use the calculator, Juno in each of the twelve signs and houses, a worked example from a real chart, how Juno differs from Venus and the 7th house, and the mistakes people make when they search their chart for a soulmate.
Juno (asteroid 3) was discovered in 1804 and named after the Roman queen of the gods, wife of Jupiter. In mythology she was the protector of marriage and women, famous for her loyalty and her fury at betrayal. Modern astrologers, especially following Demetra George's work on the asteroid goddesses, use Juno to describe:
Commitment style: what you need to feel secure in a lasting partnership.
Ideal spouse qualities: the traits you value in a long-term partner.
Equality and fairness: how you handle power, roles and respect in a relationship.
Jealousy and betrayal: where you feel most vulnerable to disloyalty.
Contracts and agreements: beyond romance, Juno also describes business partnerships and binding commitments.
Venus shows attraction, pleasure and values. You might feel strong Venus chemistry with someone who would never make a good spouse for you. Juno filters for staying power: shared responsibilities, loyalty and the practical side of partnership.
Open the Astrology Geeks Juno sign calculator and enter your birth date, time and city.
The result shows Juno's sign and exact degree. Juno's speed varies, so people born a few weeks apart can have different Juno signs.
The house shows the life area where commitment matters most to you, or where you may meet a long-term partner.
A retrograde Juno suggests rethinking ideas about marriage over time. Aspects to Venus, the Sun, the Moon or the Descendant strengthen Juno's role in the chart.
Needs an independent, brave, direct partner. Values honesty and passion; hates feeling controlled.
Needs loyalty, stability and physical affection. Seeks a reliable partner who shares material goals.
Needs mental connection and communication. A partner who is curious, witty and willing to talk everything through.
Needs emotional safety and family orientation. Seeks a nurturing partner and a shared home.
Needs admiration, loyalty and romance. A partner who celebrates them and is proud to be seen with them.
Needs practical partnership and mutual support. Shows love through helpful acts and expects reliability in return.
Juno is at home here, as Libra is the sign of partnership. Needs equality, fairness, beauty and harmony. Marriage is very important to them.
Needs depth, intimacy and total loyalty. Intense commitments; betrayal is the deepest wound.
Needs freedom, adventure and shared beliefs. A partner who is also a travel companion and fellow seeker.
Needs maturity, ambition and a long-term plan. Often marries someone established or older.
Needs friendship, space and an unconventional arrangement. A partner who respects individuality.
Needs spiritual and emotional connection. Seeks a compassionate, imaginative partner; must watch for idealising.
1st house: partnership is part of identity; may marry early or be seen as a natural partner.
2nd house: shared values and finances are central; security matters.
3rd house: communication is the core of commitment; may meet a partner locally or through study.
4th house: home and family are the purpose of marriage; may marry for roots.
5th house: romance and play keep commitment alive; children may be important.
6th house: daily routines and service; partners may meet at work.
7th house: Juno's natural house; strong focus on marriage and equal partnership.
8th house: intense, transformative bonds; shared resources and intimacy are key.
9th house: a partner from another culture or met through travel or study.
10th house: marriage linked to career or status; possibly a public partnership.
11th house: a partner who is also a best friend; meeting through groups.
12th house: a private or spiritual bond; possible hidden or idealised relationships.
Take a chart for 14 June 1994 at 08:30 in London. The calculator places Juno at 17° Libra in the 4th house, just past the IC (16° Libra).
Sign: Libra. Juno is in its most natural sign. This person values equality, fairness and harmony in marriage, and takes commitment very seriously.
House: 4th, conjunct the IC. Commitment is deeply connected to home, family and emotional roots. The ideal partnership is one that builds a shared, beautiful home base.
Aspects. Juno makes a wide trine (about 6 degrees) to the Gemini Sun at 23°, so commitment supports the person's sense of identity. Venus at 29° Cancer is in a sign square to Libra but 12 degrees too wide for a true aspect; still, the Cancer-Libra tension hints that romantic attraction (Venus) and long-term needs (Juno) do not always point to the same person.
Synthesis: someone who wants a balanced, home-centred marriage, may choose a partner partly for family values, and must learn to tell apart short-term attraction and genuine compatibility.
Juno can also help with timing. Astrologers watch for these periods:
When Jupiter or Saturn crosses your natal Juno degree, commitment questions tend to come up: engagements, moving in together, signing contracts or ending partnerships that no longer feel fair. Jupiter tends to expand and bless; Saturn tends to formalise or test.
Juno circles the zodiac in about 4.4 years. When it crosses your Venus, Descendant or 7th house ruler, relationship themes are highlighted for a few weeks.
Juno moves slowly enough by secondary progression that a sign or house change over a lifetime is meaningful. A progressed Juno entering your 7th house, or stationing direct, often coincides with a new attitude toward marriage.
Venus: what you find beautiful and pleasurable; attraction.
Descendant and 7th house: the type of person you are drawn to as a partner and how partnerships unfold.
Juno: what makes you feel committed and secure over years; the "spouse" filter.
Reading all three together gives a much more complete relationship picture than any one on its own.
Juno is especially useful if you keep repeating the same relationship pattern, if you feel strong attraction to people who never commit, or if you are deciding whether a long relationship should become a marriage. Comparing what Juno says you need with what your current relationship provides is a practical, honest exercise.
Juno for single people
If you are single, Juno is useful as a filter: before committing, check whether a new partner genuinely offers the qualities of your Juno sign and house.
Treating Juno as a soulmate locator. It describes needs and commitment style, not a specific person.
Using Juno without Venus and the 7th house. Juno works best as part of the relationship picture.
Ignoring the house. It shows where commitment matters most.
Assuming Juno only applies to marriage. It also covers business partnerships and binding agreements.
Overstating small aspects. Use tight orbs (about 2 to 3 degrees) for asteroids.
It describes what you need in a committed partner and how you approach marriage, loyalty and fairness in long-term relationships.
Enter your birth date, time and place in a Juno sign calculator. It will show Juno's sign, degree and house.
It shows the qualities you are drawn to in a spouse and what you need to stay committed, not a specific person.
Venus describes attraction and pleasure; Juno describes long-term commitment and partnership needs.
Yes. Juno contacts between charts, especially to the Sun, Moon, Venus or Descendant, are often found between long-term partners.
Your Juno sign is a quiet but revealing part of your chart, showing what you need to commit and stay committed. Find it with the calculator, read the sign and house together, and compare it with your Venus and 7th house for a full relationship picture. For more calculators and guides, explore Astrology Geeks.
