Frequently Asked Questions
Does the calculator include the start and end dates?
Yes, both the start date and end date are included in the working days count. This is the standard convention for business day calculations.
How do I add custom holidays?
You can either select a preset (US Federal, UK Bank Holidays, etc.) or manually add dates using the "Add" button. Each holiday will be excluded from the working days count if it falls within your date range.
What if a holiday falls on a weekend?
If a holiday falls on a day already marked as a weekend, it won't be double-counted. The day is simply excluded once.
