Portugal — Janeiro 2026

Portugal businesses have 21 working days in Janeiro 2026 — that's 31 calendar days minus 9 weekend days and 1 weekday public holiday (New Year's Day). The depth of Northern-hemisphere winter and Southern-hemisphere summer typically governs the work-rhythm in Janeiro; project deadlines and payroll cycles in Portugal 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, Janeiro 2026 contains 4 full work-weeks plus 1 additional weekday, 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 Portugal payroll-period calculations.
