Accurately calculate the number of business days by automatically excluding weekends and custom holidays.
Still counting working days manually? This tool automatically calculates the number of business days between two dates, accurately excluding weekends and custom holidays to output an exact working day count. It is ideal for project scheduling, payroll tracking, and attendance management.
Date inputs must follow the YYYY-MM-DD format. A maximum of 30 custom holiday dates is supported. Results are for reference only and are not legally or contractually binding. All calculations are performed locally in your browser, ensuring no data upload risks.
For cross-timezone projects, we recommend using UTC dates to avoid time difference errors. Common use cases include calculating project durations (e.g., 2023-09-01 to 2023-09-30, excluding the Mid-Autumn Festival, results in 21 business days) and tracking monthly attendance. Holiday data should be updated regularly to ensure accuracy.
