Sri Lanka — December 2027

Sri Lanka businesses have 22 working days in December 2027 — that's 31 calendar days minus 8 weekend days and 1 weekday public holiday (Unduvap Full Moon Poya Day). The depth of Northern-hemisphere winter and Southern-hemisphere summer typically governs the work-rhythm in December; project deadlines and payroll cycles in Sri Lanka 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, December 2027 contains 4 full work-weeks plus 2 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 Sri Lanka payroll-period calculations.
