They (kinda) exist in Finland, as lunch is unpaid, but the workday is 7.5 hours and the workweek is 37.50 hours. Lunch is often optional, but a typical workday can be from 9 to 5 with a 30 minute lunch break. There can also be two ~10min "coffee" breaks in addition to the lunch break but they typically matter only in non-software development work environments..

Is 7.5 the standard workday in Finland or are you talking only about your case? If it's typical, it's very encouraging to read about it and it explains a lot about why it's mostly Scandinavian places that are willing to experiment with 6 hours also.

By law the maximum is 40 hours per week (8 hours a day). The length of the workday is determined by a "generally binding" collective labor agreement[1]. It depends on the sector you're working in, but is often 37.50 hours per week. In the IT industry it's almost everywhere 37.50 hour per week. Some sectors have a 40 hour work weeks, but have extra days off here and there to bring the average down to 37.50 hours.
