Uranus opposition and Uranus squares calculator
The Uranus opposition is when transiting Uranus stands directly opposite Uranus in your birth chart. Astrology often links it with the midlife turning point: a threshold that shakes up habits and strengthens the wish to break free.
The tool calculates Uranus's squares and opposition to its own birth position from your birth details.

What is the Uranus opposition?
The Uranus opposition is the period when transiting Uranus stands exactly opposite (180°) natal Uranus, between ages 39 and 45. Astrology links it to the midlife turning point: a threshold that shakes up habits and strengthens the wish for freedom and renewal.
Uranus was the first planet discovered with a telescope, by William Herschel in 1781; modern astrology treats it as the planet of change, freedom, innovation, surprise and individuation. It orbits the Sun in 84 years, so over a lifetime it makes four major stops relative to its birth position: the waxing square, the opposition, the waning square and the return.
The opposition is the exact midpoint of the cycle: the order built in the first half of life is seen from the perspective of postponed wishes and undiscovered talents.
At what age is the Uranus opposition?
The Uranus opposition happens between about 39 and 45, depending on birth year. The difference comes from Uranus changing speed along its elliptical orbit.
- Born 1930–1960
- About age 39–41.
- Born around 1965
- About age 40–41.
- Born 1970–1995
- About age 42–44.
- Born 2000–2010
- About age 42–43.
- Born 2015–2030
- About age 39–41.
These values were calculated with the AstroSitus ephemeris engine for sample birth years; use the form for your own dates.
Why does the Uranus opposition age depend on birth year?
Uranus's orbit is slightly elliptical: it moves faster near perihelion (last around 1966) and slower near aphelion (last around 2009). Moving 180° away from its birth position therefore takes less time for some generations and more for others.
On average Uranus crosses a sign in 7 years, but it crosses the signs in its fast stretch more quickly and those in its slow stretch more slowly. The same applies to the squares: the waxing square varies between 18 and 23, the waning square between 60 and 65.
That is why a single figure such as "the Uranus opposition happens at 42" is misleading; the correct date only comes from a personal calculation.
The Uranus opposition and the midlife crisis
The Uranus opposition is the most cited astrological marker of the so-called midlife crisis, but it does not come alone. In the same decade come the Saturn opposition (ages 43–46), the Neptune square (about 39–42) and, for some generations, the Pluto square.
The overlap of these transits makes the forties an intense time of questioning life's direction. Astrology reads this not as an unavoidable crisis but as a window for making a long-postponed change consciously: a new career, a creative pursuit, more freedom in a relationship or a bold change in lifestyle.
When are the Uranus squares?
The waxing Uranus square happens around ages 18–23 and the waning Uranus square around 60–65. The opposition lies between them.
- Waxing square (age 18–23)
- The first rise of independence: leaving the family home, searching for your own path and identity.
- Opposition (age 39–45)
- The threshold of change: routines are shaken, postponed wishes surface, a new direction is sought.
- Waning square (age 60–65)
- Restructuring: the transition to retirement, settling freedom into a new order.
- Uranus return (about age 84)
- Completing the cycle: looking at life afresh and reclaiming your originality.
What happens during the Uranus opposition?
Astrology interprets the Uranus opposition through unexpected change, the wish for freedom and the need to rearrange life's patterns. How disruptive the change feels is also linked to how much room you make for it.
Commonly described themes: changing careers or starting your own business, moving, taking up a new field of study or hobby, wanting more space in relationships, discovering a suppressed side of yourself. The house of Uranus in your birth chart and the opposite house the opposition falls in show where the change will happen.
The Uranus opposition by house
An opposition plays out along an axis: transiting Uranus moves through the house opposite the one natal Uranus occupies. The topics of both houses therefore come up together.
1st–7th house axis
A new balance between your own identity and your relationships; a need for freedom in partnerships.
2nd–8th house axis
Personal income and shared resources; a radical change in how you see money and value.
3rd–9th house axis
Everyday thinking and philosophy of life; new study, travel or a change of belief.
4th–10th house axis
Home and family versus career; moving house or a change of professional direction.
5th–11th house axis
Personal creativity and community; new circles, creative freedom.
6th–12th house axis
Daily routine and inner life; rebuilding how you work and your health habits.
How is the Uranus opposition calculated?
AstroSitus finds the natal longitude of Uranus and uses its own ephemeris engine to search ages 0 to 90 for every moment transiting Uranus is 90°, 180° and 270° from that point and when it returns to it.
The historical time zone of your birthplace is found automatically and the birth moment is converted to UTC. Uranus's position is sampled at close intervals; every interval where the angle changes sign is narrowed using the planet's speed down to the exact hit. Uranus is retrograde for about five months a year, so the opposition usually has three hits, grouped under one event.
Uranus moves so slowly that not knowing your birth time makes practically no difference to the dates.
Common misconceptions about the Uranus opposition
The Uranus opposition does not happen at 42 for everyone, does not bring a guaranteed crisis and does not happen on a single day.
- "Everyone has it at 42."
- It varies between 39 and 45 depending on birth year.
- "It always means divorce or losing your job."
- The tradition speaks of a need for change; change can also come through conscious choices, step by step.
- "It's a one-day event."
- The three exact hits usually span more than a year.

Frequently asked questions
What is the Uranus opposition?
It is transiting Uranus making a 180° angle to Uranus in your birth chart. It happens between ages 39 and 45 and is interpreted in astrology through change, rediscovery and breaking old patterns.
At what age is the Uranus opposition?
Between about 39 and 45, depending on birth year: around 39–41 for people born 1940–1965, 42–44 for 1975–1995 and 42–43 for the 2000s. Use the AstroSitus calculator for your exact dates.
How long does the Uranus opposition last?
Because Uranus goes retrograde, the opposition usually has three exact hits spread over close to a year. Including the approach, interpretation treats it as a two-year period.
Is the Uranus opposition the midlife crisis?
It is astrology's most cited marker of the midlife turning point. The Saturn opposition and Neptune square fall in the same decade; but the period is read not as a mandatory crisis but as a chance to make room for change.
When are the Uranus squares?
The waxing square comes around ages 18–23, the waning square around 60–65. Both appear with dates on this page's timeline.
Does it show the Uranus return too?
Yes. The Uranus return comes around age 84; it falls within the calculation range (ages 0–90), so it is listed.
Why isn't it the same age for everyone?
Uranus's elliptical orbit changes its speed: it moves fast near the Sun (around 1966) and slowly far from it (around 2009). The time it takes to move 180° from its birth position therefore differs between generations.
Is the calculation accurate without a birth time?
Yes. Uranus moves so slowly that the birth time practically does not change the dates. The time is only needed to find which house the opposition falls in.
What should I do during my Uranus opposition?
The tradition suggests making postponed changes consciously and step by step: learning a new skill, loosening your work routine, making room in the area of life that feels stuck.
Is the Uranus opposition the same as the Saturn opposition?
No. The Saturn opposition is the midpoint of the 29.5-year cycle and also comes around ages 43–46; the Uranus opposition is the midpoint of the 84-year cycle. For some generations the two fall very close together.
Is the Uranus opposition calculator free?
Yes. The Uranus squares, opposition and return are calculated free without an account; free members also get detailed readings.
Can I ask an AI astrologer about my Uranus opposition?
Yes. In AstroSitus's AI astrologer section, the horary advisor inspired by William Lilly is open to free members. Ask a clear question such as "Should I start my own business now?" and it gives a reasoned answer from the chart of the moment you asked.
Can an AI astrologer read my birth chart?
For AI birth chart readings, AstroSitus is preparing a relationships and birth chart advisor inspired by Evangeline Adams; it is not open yet. The William Lilly advisor open today works with horary astrology: instead of your birth chart, it reads the chart of the moment you ask. Just type your question as you would to an online astrologer; free members get a daily question allowance.
