Brunei — January 2027

Brunei businesses have 20 working days in January 2027 — that's 31 calendar days minus 10 weekend days and 1 weekday public holiday (Isra and Mi'raj). The depth of Northern-hemisphere winter and Southern-hemisphere summer typically governs the work-rhythm in January; project deadlines and payroll cycles in Brunei should account for the holiday days listed above. January opens the global calendar with New Year's Day observed in nearly every country and several civic holidays unique to the southern hemisphere. For pay-period planning, January 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.
