Working day adjusted series

In a working day adjusted series, the factors caused by the variation in the number of weekdays are taken into account. This means taking into consideration the lengths of months, different weekdays and holidays. Working day adjusted figures are published on industries where the variation in the number of working days has a significant effect on the time series. In comparison to trading day adjustment, working day adjustments do not pay attention to the effect of different weekdays (i.e. the effect of Fridays is not estimated separately).
