8-16 each day is 40 hours not counting the breaks. (Counting them would make it 37)

So do Swedish people work from 8-16, 9-5 or do office workers work from 8-17, 9-6 everyday (inkluding Friday)?

I have family in Malmö and that is not the case for them. Can’t speak in the standard for Sweden but I worked closely with Norwegians and they had the same 8-16 (8-15 Friday) in Oslo as we did in in Denmark(KBH).

That seems like a US thing? All Nordic Europe countries 8-16 is the US version of 9-5. 8-17 (9-6) would be a 4 days a week job hitting the normal 37 hour work week.
