Well I work and live in Sweden (notice I put work first?) and it's far from 6hrs/day for most industries. Actually now that I think about it I don't know a single person who only works 6 hours per day. The idea is great though, wish it were true :/
If you're a professional/salaried you work as much as the job requires, just like the US.
This adds up to the legal 5 weeks (25 days), for a total of 7 weeks (35 days). It's pretty common to use half a day here and there, basically reducing your work week.
So it's clearly not "just like the US".
