Thailand — ديسمبر 2026

Thailand businesses have 20 working days in ديسمبر 2026 — that's 31 calendar days minus 8 weekend days and 3 weekday public holidays (King Bhumibol's Birthday Observed, Constitution Day, New Year's Eve). The depth of Northern-hemisphere winter and Southern-hemisphere summer typically governs the work-rhythm in ديسمبر; project deadlines and payroll cycles in Thailand should account for the holiday days listed above. December centres on the Christmas long weekend in Christian countries and a cluster of solstice and winter-celebration days globally. For pay-period planning, ديسمبر 2026 contains 4 full work-weeks plus 0 additional weekdays, useful when scheduling milestones or quarterly reviews. The working-day count above counts substitute days as a single deduction — it does not double-count when a public holiday falling on a weekend is moved to a Monday or Friday. Use this figure as the authoritative baseline for Thailand payroll-period calculations.
