How many man hours are there in a year?
It is widely known the fact that a man-hour or person-hour is the amount of work performed by the average worker in one hour. This concept is extremely useful. It can be used to estimate the impact of staff changes on the amount of time required for a task. The number of man hours per year depends from one country to another. For example, in Netherlands there are approximately 1389 hours. Moreover, in South Korea there are 2316 hours. This is quite a difference.
