For the Business Days Calculator, a clear answer starts with a clear scope. The page is built to count Monday-through-Friday dates between two entered dates without removing public holidays; the formula, example, and limitations below explain what the result means and where the simplified model stops.

What this calculator does

For the Business Days Calculator, the primary output is the page’s weekdays between dates. Supporting values include Calendar days. Every value shown by the Business Days Calculator comes from the visible fields used by this rule. In practical terms, it is best used to count Monday-through-Friday dates between two entered dates without removing public holidays.

How to use it

Enter Start date and End date. For the Business Days Calculator, use the exact calendar dates you want to compare. When comparing two Business Days Calculator scenarios, change one input at a time and keep the other entries unchanged so the source of the difference stays clear.

How the calculation works

For the Business Days Calculator, the page walks from the earlier date through the later date and counts Monday through Friday, including qualifying endpoints. Saturdays and Sundays are excluded; public holidays are not.

Example

For the Business Days Calculator, using the page defaults—Start date = 2026-01-01; End date = 2026-12-31—produces 261 business days for the weekdays between dates. If the Business Days Calculator result differs, recheck the exact dates and whether its counting convention matches the interval you intended.

How to interpret the result

For the Business Days Calculator, read the weekdays between dates as the result of the specific inputs and rule described above. It is most useful when you want to count Monday-through-Friday dates between two entered dates without removing public holidays. For a Business Days Calculator comparison, keep the unchanged fields identical and vary only the value you actually want to test; that prevents a second assumption from being mistaken for the effect you are measuring.

Limitations and notes

For the Business Days Calculator, the calculator removes weekends only. For the Business Days Calculator, it does not know country-specific public holidays, company closures, settlement calendars, or whether a deadline rule counts the first or last day differently.
