In Poland it's 20 or 26 days off, all state holidays are added on top of that (there are few days, probably around 8). All of those are paid. Except those one can also take unpaid vacation but that has to be negotiated with the employer.

20 days is until you have 10 years of work experience, but graduating counts as 8 years of experience so most people just have to work 2 years to jump to 26 days.
