Select year and lunar month. Candidate dates use −1…+1 days around conjunction (see generator). Tile colors: “Visibility class” shows A–F / A–D only (same class = same color everywhere). “Numeric score” uses the old Turbo-style scale for v or q inside a class (e.g. all Yallop F can still look blue-to-red by number — that is not a different visibility class).
