How Business Days Are Calculated in Practice
Under commercial agreements, project timelines, and employment policies, a business day is defined as any weekday on which commercial banks and clearing networks are fully operational. Weekend rest days and official public holidays pause normal settlement and contractual timelines.
When planning leave or project sprints, you can pair this calculator with our PTO Maximizer to optimize vacation bridges, or check our guide on weekend holiday rollover rules to see how observed in-lieu days work when a holiday lands on a weekend. If your business coordinates international transactions, review our analysis of European TARGET2 settlement halts.
Workweeks run Sunday through Thursday in Saudi Arabia and Egypt, observing Friday and Saturday as rest days. Weekday counting adjusts automatically.
Frequently Asked Questions
How do you calculate working days between two dates?▾
To calculate working days, count the total calendar days between your start and end dates, subtract the weekly weekend rest days (typically Saturdays and Sundays), and subtract any official public holidays that fall on weekdays.
How many working days are there in 2026?▾
The year 2026 has 261 total weekdays (Monday through Friday). Depending on your country, public holidays typically reduce this number by 8 to 14 days, resulting in approximately 248 to 253 net working days for full-time staff.
How do you calculate 10 business days from today?▾
To find a date 10 business days from today, start on the next business day and count forward 10 days, skipping all Saturdays, Sundays, and official public holidays. On average, 10 business days equals 14 to 16 calendar days.
Do working days include bank holidays?▾
No. Standard working days exclude official public and bank holidays because commercial clearing banks, government offices, and standard business operations are paused.
How do invoice Net 30 payment terms count business days?▾
Standard Net 30 or Net 60 invoice payment terms count calendar days rather than working days. However, if the final due date falls on a weekend or public holiday, payment is customarily due on the next open business day under commercial contract conventions.
