Business Day Calculator

The Business Day Calculator determines the actual number of working days within a selected date range while distinguishing weekends, public holidays and adjusted working days. It also calculates a target date after a specified number of business days.

Calculate Working Days Between Dates

Enter a start date and end date to calculate total days, working days, weekends, public holidays and adjusted working days. You can choose whether the start and end dates are included.

Actual Working Day Calculation

Actual working days may require more than simply excluding Saturdays and Sundays. Public holidays and special working-day adjustments can also affect the result. The calculator separates these date types for easier verification.

Business Day Offset

Calculate a target date by moving forward or backward by a specified number of business days from a starting date. You can also control whether the starting date counts toward the calculation.

Daily Date Details

The result can include each date, its weekday and its status, helping you verify whether a date is a working day, weekend, public holiday or adjusted working day.

Common Uses

• Leave planning: Calculate actual working days during a leave period.
• Project scheduling: Estimate delivery dates based on working days.
• Deadline calculation: Find a target date after a specified number of working days.
• Attendance checking: Review working days, weekends and holidays.
• Date planning: Schedule meetings, tasks and deliveries based on working-day rules.

Holiday and Workday Rules

Public holidays and adjusted working days vary by country, region and year. For payroll, contracts, employment deadlines or other official purposes, always verify the applicable official holiday calendar and workplace rules.

Important Notes

Some organizations use special schedules such as rotating shifts, alternate weekends or custom holidays. The general calculation may therefore differ from an individual company attendance system.
