FAQ
Business days and working days questions
How do I calculate business days between two dates?
Choose Business days between dates, enter the start and end dates, select the weekend pattern, add relevant holidays, and decide whether to include the start and end dates.
Can I add 30 business days to a date?
Yes. Choose Add business days, enter the start date and 30, then configure weekends and custom holidays to calculate the resulting working-day deadline.
Can I subtract working days from a date?
Yes. Choose Subtract business days to move backward through working days while excluding the selected weekend pattern and custom holidays.
Does the calculator exclude public holidays automatically?
No universal holiday list is assumed because holidays vary by country, state, province, region, employer and year. Add the exact public holidays or closure dates relevant to your calculation.
Can I use Friday and Saturday as the weekend?
Yes. Select Friday and Saturday, Sunday only, Saturday and Sunday, or define a custom set of non-working weekdays.
Can this be used as a delivery date or SLA due date calculator?
Yes. Add business days to a starting date and include carrier closures, public holidays or company shutdown dates. Confirm binding deadlines with the responsible provider or contract owner.
What is the difference between calendar days and business days?
