from〜to間の営業日数を数えます。既定では「fromを含まず、toを含む」境界です(例:「今日から支払期日まで何営業日か」)。include_from/include_toで境界を変更できます。土日・日本の祝日を除外し、calendar="banking"を指定すると銀行休業日(12/31〜1/3)も除外します。from > to の場合はエラーにせず、from/toとinclude_from/include_toを入れ替えて計算した結果の符号を反転した値(負の営業日数)を返します(反対称則: count(A,B,x,y) = -count(B,A,y,x)。A≠B、すなわちfrom≠toの場合に成立する恒等式で、from===toはこの分岐に入らないため対象外)。入力例: {"from": "2026-07-10", "to": "2026-07-20"}
