How Business Days Are Counted
Business days = all days between two dates, excluding Saturdays and Sundays. This calculator does not account for public holidays (Memorial Day, Christmas, etc.) as these vary by country and employer. Add holiday adjustments manually if needed.

Frequently Asked Questions
Does this include public holidays?
No — the calculator only excludes weekends. US federal holidays (New Year's Day, MLK Day, Presidents' Day, Memorial Day, Juneteenth, Independence Day, Labor Day, Columbus Day, Veterans Day, Thanksgiving, Christmas) should be subtracted manually if relevant to your situation.
When does a business day start and end?
Standard US business hours are 9 AM – 5 PM ET. For legal or contractual deadlines, check the specific agreement — some define 'business day' explicitly.
