Seasonal adjustment is a statistical method, which eliminates the seasonal component of time series and it is particularly suitable for long-term comparisons and analysis of the data.

Work day adjustment is an adjustment for variations in monthly data, caused by calendar effects, different number of calendar and work days in the month, and national holydays - for example the presence of more days off in May could contribute to the decline in the production in some activities.
