FAQ
What is a business days calculator and how does it work?
A business days calculator counts the number of working days between two dates after subtracting weekends and optional regional holidays.
What’s the difference between business days and calendar days?
Calendar days count every day on the calendar. Business days typically exclude Saturdays, Sundays, and public holidays.
How are “observed” holidays handled?
When a holiday falls on a weekend, many regions observe it on an adjacent weekday (e.g., Monday). Turn on “Use observed rules” to exclude it.
Can I add my own company or local holidays?
Yes. Use Custom holidays to add dates like company shutdowns, local bank holidays, or events.
Which countries and regions are supported?
We currently support holiday sets for the United States, Canada, and the United Kingdom, plus a generic EU set.
How do I calculate the next business day from a given date?
Set the same date for Start and End, then click a preset like Next 7 days and adjust until you find the first non-weekend date.
How do I handle Net 15 / Net 30 / Net 60 payment terms?
If your agreement specifies business days, count forward using our tool with weekends/holidays excluded.
What’s the best way to schedule payroll around holidays?
Use the calculator to check if pay dates land on a holiday or weekend. Many teams run payroll one or two business days earlier.
How do business days affect filing legal documents and deadlines?
Courts and agencies often specify business-day rules and observed holidays. Always verify local rules.
How should I use business days for shipping lead times and SLAs?
Many carriers define handling time in business days and exclude weekends/holidays from delivery estimates.
Can I export my business-day results?
Yes. Click Download CSV to export the list of included dates and holiday labels.
Does the calculator account for half-days or regional early closures?
Not automatically. Add local closures as custom holidays so the tool excludes them fully.
Time zones: which one does the tool use?
Dates are interpreted based on your device’s local time zone.
How accurate are the holiday sets?
We follow common public/bank-holiday rules for each region, but local observances can vary.
Can I plan projects by business days (e.g., “15 business days from kickoff”)?
Yes—pick kickoff and target dates to ensure your timeline excludes weekends/holidays.
