Jupiter · about 12 years
Returns and oppositions review confidence, learning, horizons and the meaning you give to an opportunity.

Five clocks · one life
Jupiter opens chapters, Saturn gives them structure and the slow planets mark turns that occur only once or twice. See when they meet the places they occupied when you were born.
How to read this map
The same year may contain a Jupiter opening, a Saturn test and a deep slow-planet change. The key is to recognise the question each clock brings.
Returns and oppositions review confidence, learning, horizons and the meaning you give to an opportunity.
Its four quarters speak of structure, limits, work, commitments and decisions that need to mature.
It marks turns in freedom and authenticity. Its opposition often arrives in midlife, but not at the same age for everyone.
We travel only part of its orbit. Its contacts review ideals, sensitivity, faith, confusion and boundaries.
Its speed varies greatly by generation, so a Pluto square must not be calculated from a fixed age table.
What is actually calculated
First, the zodiacal longitude of each planet on your birth date is found. Then the app searches for the dates when the moving planet reaches that degree or forms a 90° or 180° angle. Every crossing is refined and retrograde repeats are included.
Jupiter, Saturn and the outer planets move very little during one day. For this kind of cycle, asking for time and place would barely change the useful date and would suggest false precision.
From Earth, a planet can appear to move forward, backward and forward again over the same degree. These are not separate cycles, but exact contacts within one process.
The dedicated calculator goes deeply into the three Saturn returns. This app places Saturn beside four other clocks and adds squares, oppositions and a shared timeline.
No. The astronomical calculation marks contacts between positions; their interpretation belongs to the symbolic language of astrology. A cycle can help you ask better questions, but it does not make events inevitable.
