Brunei — 2027年12月

Brunei businesses have 20 working days in 12月 2027 — that's 31 calendar days minus 9 weekend days and 2 weekday public holidays (Christmas Day, Isra and Mi'raj Observed). The depth of Northern-hemisphere winter and Southern-hemisphere summer typically governs the work-rhythm in 12月; project deadlines and payroll cycles in Brunei 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 Brunei payroll-period calculations.
