The study shows the dogmatic effect of the specific legal nature of public holidays on the organization and remuneration of working time. This effect can be seen in the duality that the public holiday affects (reduces) the duration of the parties' performance on the one hand, but also affects the conditions of actual performance, mainly because working time can only be prescribed under special conditions. But this duality also determines the dogmatics of public holiday pay rules: the legislature compensates for the reduced working hours due to public holidays, on the one hand, and the “inconvenience of work” that an employee performs on public holidays, on the other.
