What counts as a crossing?
Each pair has two opposite zodiacal midpoint locations, which form one 180° axis. We fold that axis to 90° and search four zodiacal longitudes, each 90° apart. These include a transit over either end of the midpoint axis and squares to it. The table reports the target zodiac degree and its common 90° dial coordinate. It does not turn those four longitudes into one physical place in the sky.
A moving planet can cross the same target more than once around a retrograde station. Search results show each crossing found by hourly bracketing and minute-rounded refinement. Exact contacts are geometric dates, not forecasts of events or evidence that a midpoint interpretation is true. Read the method guide before using a close date.
