The three harmonies (三合) are four branch trinities, each combining to one element.

Each trinity is built from a growth branch, an emperor (peak) branch and a storage branch.
Half harmony
This site applies the strict mainstream rule: two of the three branches form a half harmony only when the emperor branch is one of them.
Transformation
A trinity transforms only when its element matches the month branch.
