Thailand — 2027年12月

Thailand businesses have 20 working days in 12月 2027 — that's 31 calendar days minus 8 weekend days and 3 weekday public holidays (King Bhumibol's Birthday/Father's Day Observed, Constitution Day, New Year's Eve). The depth of Northern-hemisphere winter and Southern-hemisphere summer typically governs the work-rhythm in 12月; 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, 12月 2027 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.
