The exact opposition separates within hours, but the review it opens does not close on October 26. Venus stays retrograde until mid-November, and Mercury runs retrograde from October 24 to November 13. The full moon is where you name the position; the following two weeks are where you test whether the named position holds when someone pushes back.
Expect the pushback to arrive as a question about fairness. Venus retrograde at 29.52° Libra holds the Sun axis at 3.24°, so fairness is the live question, not force: is this split still even, is this favour still mutual, is this price still the one you agreed to. Answer with the number you wrote down in the decision check. If the number has changed, say so plainly instead of reaching for a softer word.
This is also when the wide background contacts earn their keep. Mercury square Jupiter at 2.8397° invites you to over-explain, to build a case, to reopen the whole history. Resist that. One paragraph, one number, one date.
To see which part of your life carries this, you need more than a Sun sign. The free transit chart calculator compares the transiting planets with your birth chart at a chosen date. Enter your birth date, time and place, set the date to October 26, 2026, and select your location.
One practical note: a full personal picture needs an accurate birth time and location, because the rising sign, houses and angles depend on them. A date alone cannot give you those. If you do not know your birth time, the moon sign calculator will show you when your Moon sign shifts that day, which tells you whether your Moon placement is safe to read from a date alone.
Name the thing. Price it. Check it against your own chart. The full moon does not decide for you — it just refuses to let the word 'complicated' stand in for a sentence you already know how to finish.
