Business day note
This calculator assumes Saturday and Sunday weekends and only excludes the holiday dates you enter. Confirm local calendars before using the result for contracts, payroll, or shipping promises.
A business days calculator counts weekdays between two dates and excludes weekends.
You can add custom holiday dates when company, country, or market closures should not count as working days.
Confirm end-date rules
Deadlines often differ on whether the final day should be included in the count.
Add local holidays manually
Holiday calendars vary by region, company policy, exchange, and legal jurisdiction.
Example
A date range can include calendar days, weekend days, and fewer actual business days.

Forgetting local holidays
The calculator cannot know every country, exchange, school, or company calendar. Add holidays manually when they should be excluded.
Mixing inclusive and exclusive ranges
Some teams count the final date and others do not. Confirm the rule before using the result in deadlines or contracts.
Treating business days as legal advice
Use the count for planning. Legal, payroll, court, shipping, or compliance deadlines may use special rules.
Can I include the final date?
Yes. Use the include end date checkbox.
Are holidays automatic?
No. Add holiday dates manually so the result matches your country or company.
Can the end date be before the start date?
Yes. The calculator counts the absolute range between the two dates.
How is the date math processed?
The date math is handled in the browser for this tool based on the current public implementation.
