In this paper, the data from the multi-purpose survey on household "Time Use" conducted by Istat (the Italian National Statistical Institute) in 2002-2003 and the data from this same survey conducted in 1988-1989 will be analysed with the purpose of describing the fathers' daily participation in the domestic activities and of highlighting the changes that have taken place during the 14 years elapsed between the two survey editions. The analysis will be carried out using standard time-use data analysis' tool, time budget tables and by applying a multi-variate regression model with the objective of separating the relative contribution of the behavioural and structural factors to explain the variation observed.
