Use this when you need the number of official mainland China working days in a 2024-2026 date range for an SLA, payroll, project or delivery estimate. 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 only elapsed calendar days, another jurisdiction, an industry-specific settlement calendar, or dates outside 2024-2026. What it computes: Counts official mainland China working and non-working days in a date range using State Council holiday periods and weekend makeup workdays rather than a simple Monday-Friday rule.
