When an eligible public holiday falls on a weekend or overlaps another holiday, the next working day becomes a substitute holiday. 2026 has five substitute holidays: 2 March, 25 May, 17 August, 28 September, and 5 October. Memorial Day (Saturday, 6 June) is not eligible and gets no substitute.
Not officially. Workers' Day (1 May) is a paid day off for employees covered by the Labor Standards Act — most private-sector workers — but it is not a designated public holiday, so government offices and schools stay open.
