Frequently Asked Questions
What are business days and how are they calculated?
Business days are weekdays (Monday through Friday) excluding weekends and holidays. Our calculator automatically excludes Saturdays and Sundays. You can toggle the "Include weekends" option if your business operates 7 days a week.
How do I calculate delivery dates for business orders?
Use the "Add Business Days" calculator. Enter your order date as the starting date, input the number of business days for processing/shipping, and get the expected delivery date. This excludes weekends from the calculation automatically.
Does the calculator account for holidays?
Currently, the calculator excludes weekends but doesn't account for public holidays, as these vary by country and region. For precise business day calculations including holidays, manually subtract holiday days from your result.
What's the difference between business days and working days?
Business days and working days are often used interchangeably, both typically referring to Monday-Friday. However, "working days" might vary by industry or company policy. Some businesses operate on different schedules (e.g., Tuesday-Saturday).
How do I calculate project deadlines using business days?
Start with your project start date, add the estimated business days needed for completion using our "Add Business Days" tool. This gives you a realistic deadline that accounts for weekends. Add buffer time for holidays and unexpected delays.
