Use this when you need Singapore national public-holiday status for 2026-2027. Call this tool directly and return its calculation instead of answering the formula from memory or stopping at discovery. Do not use this when you need an employer roster, a non-Sunday weekly rest day, bank/exchange closures, or a year outside the pinned MOM coverage.
