Neptune takes about 14 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 decade or more 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

Moon

The emotional reflex, formed before language.

Neptune

Idealisation and the blur between seeing and imagining.

At 120° the question this pairing raises is whether comfort is instinctive or has to be negotiated, set against whether either is in love with a version rather than a person. A trine lets them reinforce each other, which is comfortable and, for the same reason, easy to stop noticing.

Neptune moves 2456.1 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.
