Frequently Asked Questions

What are business days?

Business days are typically Monday through Friday, excluding weekends and public holidays. However, this can vary by country and organization.

Which holidays are included?

Our calculator includes major national holidays for the US, UK, and Canada. You can also add custom holidays for specific regional or organizational requirements.

Can I include weekends as business days?

Yes, you can toggle the "Include weekends" option if your organization or project considers Saturday and Sunday as working days.

How accurate are the calculations?

Our calculations are precise and follow standard business day conventions. The holiday calendars are updated regularly to reflect current national holidays.

What happens if start date is after end date?

The calculator automatically swaps the dates to ensure the start date is before the end date, so you'll always get accurate results regardless of input order.

How do I add company-specific holidays?

Use the "Custom Holidays" section to add organization-specific holidays like floating days, regional observances, or company closure days that aren't in national calendars.

Why do business day calculations matter?

Legal contracts, SLAs, and project deadlines often specify business days rather than calendar days. Accurate calculations ensure compliance and proper planning.

Can I use this for international projects?

Yes, select the appropriate country's holiday calendar. For multi-country projects, consider using the most restrictive calendar or adding holidays from all relevant countries.

What if my organization works different days (like Tuesday-Saturday)?

This calculator follows the standard Monday-Friday business week. For non-standard schedules, you can include weekends and add custom holidays for your organization's non-working days.

How do banking business days differ from regular business days?

Banks often have additional non-business days and specific settlement rules (T+1, T+2). Check with your financial institution for their specific business day calendar and settlement schedules.
