Chiron takes about 4 years to cross one sign. Everyone born inside that window has it in the same place, so this aspect is largely a description of the age gap between two people rather than of the relationship.

Put concretely: if you and your partner were born a few years apart, this aspect was decided by the calendar before either of you existed. Why 40.1% of searched aspects work this way →

What these two planets are doing

Chiron

The injury that became a competence.

Moon

The emotional reflex, formed before language.

At 120° the question this pairing raises is whether the same wound is being pressed or tended, set against whether comfort is instinctive or has to be negotiated. A trine lets them reinforce each other, which is comfortable and, for the same reason, easy to stop noticing.

Chiron moves 701.8 times slower than moon, so the faster one sets how long the exact angle holds.

If the birth time is wrong

This aspect survives 13.3 hours of error

0.6° per hour — how far Moon 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.
