About the Vietnam Business Days Calculator
Last Updated: July 2026
The Vietnam Business Days Calculator is a free, web-based utility designed to help professionals, project managers, and HR teams accurately count the number of working days between two dates. Unlike a standard calendar, this tool automatically excludes the standard Saturday and Sunday weekend, along with 7 major regional public holidays (such as Giỗ tổ Hùng Vương) observed in Vietnam during 2026.
Why calculate working days?
- Project Planning: Determine realistic project delivery timelines based on actual working hours.
- Leave Management: Calculate how many annual leave days are consumed when booking a vacation over a period that includes weekends and public holidays.
- Financial & Legal Contracts: Many SLAs, contracts, and financial settlements are defined strictly by "business days" rather than calendar days.
Data Source: Holiday data is aggregated from official Vietnam government gazettes and financial market schedules.

Frequently Asked Questions (Vietnam)
How many business days are there in a year? +
The number of business days in Vietnam depends on the total number of weekdays (excluding Saturday and Sunday) as well as the 7 public holidays observed. Use the calculator above to determine the exact number of business days for any specific date range.
Can public holidays affect project deadlines? +
Yes. Public holidays are typically excluded from business day calculations, which can extend project timelines, contract deadlines, and delivery schedules. Factoring in holidays helps create more accurate plans.
Why do companies use business days instead of calendar days? +
Business days reflect actual working days when offices, banks, and organizations are operating. Using business days provides more realistic timelines for projects, contracts, payments, and service-level agreements.
Can I add or subtract business days from a date? +
Yes. This calculator can determine a future or past date by adding or subtracting a specified number of business days while automatically excluding weekends and public holidays.
Are business days the same in every country? +
No. Different countries may observe different public holidays and weekend structures. While many countries use Saturday and Sunday as weekends, others may follow different schedules. This calculator automatically adjusts based on the selected country.
What is the difference between a business day and a calendar day? +
A calendar day includes every day on the calendar, including weekends and public holidays. A business day includes only official working days and excludes weekends and recognized public holidays.
How do weekends affect business day calculations? +
Weekends are excluded from business day calculations. For example, if a task starts on Friday and requires three business days, the weekend is skipped and the due date becomes Wednesday.
Can I calculate business days between two dates? +
Yes. Simply select a start date and end date, and the calculator will determine the number of business days between them while excluding weekends and applicable public holidays.
