Thailand · 2026
Thailand calculated business days for 2026: weekends, public holidays, and a monthly working-day table. Based on published holiday data — not a legal determination.
Contracts, banks, industries, regional subdivisions, and organizations may use different business-day definitions. Regional holidays appear only when the dataset supports them. This is not legal advice.

Methodology
A calculated business day is a civil calendar day that is not a weekend under the adopted weekend model and not a public holiday returned by the offline date-holidays dataset. Holidays that fall on weekends are not counted twice. LifeNaviHub computes these figures from published holiday and weekend data — they are estimates for planning, not statutory or contractual definitions.
