What these two planets are doing

Mercury

How thinking gets turned into speech.

Venus

What someone finds attractive and how they show affection.

At 120° the question this pairing raises is whether conversation flows or constantly needs translating, set against whether the same gestures read as love to both. A trine lets them reinforce each other, which is comfortable and, for the same reason, easy to stop noticing.

Mercury moves at about the same rate as venus, so the faster one sets how long the exact angle holds.

If the birth time is wrong

This aspect survives 8.1 days of error

0.04° per hour — how far Mercury moves, the faster of the two and therefore the one that decides.
the orb allowed for trine. Beyond it the aspect is no longer counted at all.
Robust Even a badly remembered birth time leaves this one standing.
