August 2025 has 20 working days and a working time norm of 160 hours.
The norm is for a full-time job in the basic working time system. Calendar days this month: 31.
The Polish Labour Code (art. 130) gives 8 hours for every Monday to Friday and takes off 8 hours for every public holiday not falling on a Sunday. This month: 21 × 8 h − 1 × 8 h = 160 h.
First working day: Friday, 1 August 2025. Last working day: Friday, 29 August 2025.
Legal basis: art. 130 of the Polish Labour Code and the Act of 18 January 1951 on public holidays (Christmas Eve off since 2025). More: working days versus the working time norm.
A tax or contribution deadline that falls on a Saturday, Sunday or public holiday moves to the next working day (art. 12 § 5 of the Tax Ordinance). Pay moves the other way.
