May 2100 has 19 working days and a working time norm of 144 hours.

The norm is for a full-time job in the basic working time system. Calendar days this month: 31.

Public holidays

How the norm is worked out

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 − 3 × 8 h = 144 h.

First working day: Tuesday, 4 May 2100. Last working day: Monday, 31 May 2100.

Part-time norms

• 1/2 of full time: 72 h
• 3/4 of full time: 108 h
• 1/4 of full time: 36 h

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.

Deadlines for this month
