How to Calculate Vacation Leave Days (Thai Labor Law)

Under the Thai Labor Protection Act B.E. 2541 (1998), employees who complete 1 year of service are entitled to at least 6 vacation days per year (companies may offer more).

Minimum Legal Entitlement

• 1 year of service → 6 vacation days/year
• Companies may add more in later years (e.g., 7-12 days)
• Unused days may carry over per company policy

Proportional Calculation

Vacation days = (months worked ÷ 12) × annual entitlement

Example: 6 months worked, 6-day annual entitlement:

• (6 ÷ 12) × 6 = 3 days

More Examples

Tenure	Entitlement (6 days/year)
3 months	1.5 days
6 months	3 days
9 months	4.5 days
12 months	6 days

Tips for HR/Employees

• State carry-over and usage rules clearly in contracts
• Plan leave outside peak seasons
• Vacation leave is paid leave
