Weekdays versus business days
A basic business-day calculation normally excludes Saturday and Sunday. Public holidays vary by country, region and organization, so they need a separate holiday calendar.
Simple method
Count each calendar date in the range and include only Monday through Friday. Decide whether the start date and end date should be included before comparing results from different services.
Deadlines
For legal, banking, shipping or government deadlines, confirm the official holiday and cutoff rules rather than relying on a generic weekday count.
Use the Business Days Calculator for a quick weekday count.
Quick answer
Count weekdays between two dates and exclude weekends. Use the values and units shown by the tool, review the result, and keep the original inputs available if you need to compare another scenario.
Practical checklist
- Confirm the units, dates, rates or source values before calculating.
- Use consistent units and avoid rounding intermediate values too early.
- Run a second scenario when you need to understand how one input changes the result.
- For regulated fees, taxes, provider rules or professional decisions, verify the current official rule before relying on the result.
