US business days with weekends and federal holidays

What counts as a US business day?

A common US business-day rule counts Monday through Friday and excludes weekends. Many business timelines also exclude federal holidays, observed holidays, bank holidays, or company holidays. The calculator lets you keep that standard rule or customize the non-working days.

When to exclude public holidays

Exclude holidays when the timeline depends on banks, public offices, payroll operations, support SLAs, or a contract that defines business days as days when offices are open. For shipping or customer-support promises, confirm whether Saturday delivery or regional company holidays change your rule.

Common US planning examples

The most common searches are 5 business days from today, 10 business days from today, 30 business days from a start date, and working days between two invoice dates.

• Payment terms: net 10 business days or net 30 business days.
• Support operations: response deadlines that skip weekends and holidays.
• Shipping estimates: delivery windows that use weekday operations.
• Payroll and HR: workdays inside a pay period or leave window.
