What does the rest day mean in the labor law?

Rest days in the labor law refer to days excluding working days and legal holidays, that is, Saturdays and Sundays in the usual sense.

If you go to work on Saturday and Sunday (overtime is arranged by the company according to law) but you don't arrange compensatory time off, you need to pay double salary.
