How Business Days Are Counted

This calculator counts Monday through Friday as business days, excluding Saturdays and Sundays, between (and including) your start and end dates.

Federal and Company Holidays Not Included

This calculator excludes weekends only — it doesn't automatically account for federal holidays (like Thanksgiving or Christmas) or company-specific holidays, since these vary by organization, industry, and country. Manually adjust the result if holidays fall within your date range.

Common Uses

Frequently Asked Questions

Does this account for public holidays?

No, this calculator excludes weekends (Saturday and Sunday) only — federal and company holidays vary by organization and location, so manually subtract any holidays that fall within your date range for full accuracy.

Why do businesses use "business days" instead of calendar days for deadlines?

Business days better reflect actual working time, since most offices, processing centers, and shipping operations don't operate on weekends — using business days gives a more realistic estimate of when work will actually get done.
