I don't know about the rest of Europe, but in Sweden everyone gets 25 vacation days a year by law, given that you work a full year.
Depending on your employer and your collective labor agreement, some people get more. I work in public health care, and I got 6 extra days when I turned 40, and another extra day when I turned 50. So I now have 32 days a year, which is maximum for me. No more extra days when I turn 60 
So what do you need holidays for?

In the U.S., an entry-level employee in a full-time job typically starts with two weeks (10 days) of vacation a year. (I interviewed for a job about seven years ago that offered one week of vacation, and I'd been in the business for 20+ years. I think one reason I didn't get the job is that I must have turned pale in shock at that point.)
So our entry-level worker gets 10 days of vacation, but typically it's actually just PTO (paid time off), and the days double as their paid sick days. Pretty much everyone gets the main federal holidays off: Christmas, Memorial Day, July 4th, Labor Day and Thanksgiving off (am I forgetting any, Americans?). If they're a nurse or police officer or newspaper reporter or someone else who
has to be on duty, they would work those days but probably get extra holiday pay. There are other federal holidays they may or may not get off, depending on the employer (Martin Luther King Day, President's Day, Columbus/Native Americans Day, Veteran's Day). And some get extra days thrown in with the holidays -- Christmas Eve, the day after Thanksgiving, etc.
So the typical entry level worker might get 15 days off a year, and hope not to be sick for many of them. An employee with more experience or a more generous employer might get more like 20-30, but no way is it guaranteed by law. (As you probably know, paid parental leave isn't even guaranteed by law here -- the U.S. being one of three countries in the world, and the only industrialized country, not to require it.)
I've been around long enough that I get five weeks of PTO at one of my jobs. It's a half-time job, so it's five weeks at 25 hours a week, but still, it's a nice little perk. We have to use our PTO days if we want holidays off, but because I work part time I just schedule my hours around them and save the PTO.
The other job is a contract job, which means I get nothing, nada, zilch. No PTO, no holidays, no sick pay. Not to mention no health or dental care, no retirement plan, no whatever other benefits real employees get. However, this job pays much better than the other job, and they do take us out to lots of lunches and dinners in nice restaurants and throw fancy parties twice a year.
