How to use
Use the Vietnam Business Days Calculator to find the exact number of working days between two dates. Enter your start date and end date. You can choose whether your workweek includes Saturdays or if it's a standard Monday-Friday schedule. The calculator automatically excludes weekends and can account for official Vietnamese public holidays (like Tet, Independence Day). This tool is essential for HR managers planning payroll, project managers setting deadlines, and logistics teams estimating delivery times in Vietnam.
How it's calculated
Business Days
Working days after removing weekends and public holidays
Non-Working Days
Total weekends plus public holidays in the period
Examples
30-day month, 8 weekends, 0 holidays → 22 business days

- Public Holidays on Weekdays:0
- Weekend Days (Sat + Sun):8
Result
- Business Days:21 days
Between August 1st and August 31st on a standard 5-day workweek, there are exactly 21 business days after excluding 10 weekend days.
30-day month, 8 weekends, 2 holidays → 20 business days
- Total Calendar Days:30
- Public Holidays on Weekdays:2
- Weekend Days (Sat + Sun):8
Result

- Non-Working Days:10
A 30-day month with 8 weekends and 2 public holidays yields 20 business days. For payroll and contractor billing purposes, this is the standard working day count for a typical Vietnamese month — use it to prorate daily rates accurately.
