The average length of working time in different countries depends on a number of economic, social and societal factors. Another important factor is the extent to which part-time work is widespread, which is less common in developing countries. In 2017, the Southeast Asian state of Cambodia had the longest average working hours worldwide among 66 countries studied. Here, the working time per worker was around 2,456 hours per year, which is just under 47 hours per week. In Germany, on the other hand, it was just under 1,354 hours per year (26 per week and 3.7 per anniversary), which was the lowest of all the countries studied.^[1]

In most countries, the weekly working hours are decreasing with increasing prosperity and higher productivity. In Germany, for example, the average weekly working time of a person not employed in agriculture and working full-time fell by almost 40 percent between 1870 and 2010. In developed countries, the average working time is therefore usually significantly shorter than in developing countries. However, there are exceptions. These include countries such as South Korea, Singapore and Taiwan which still have comparable long working hours despite high incomes.^[1]
