ATUS historical data(1965, 1975,1985) : week days and weekends

Can I distinguish between the time spent on weekdays and the time spent on weekends?

Especially for the data prior to 2003? such as 1965,1975, 1985,etc.

The variable DIARYDAY reports the day of the week when the diary was kept and is available for all samples in the AHTUS-X. Using this variable you can compare time-use on weekdays to time-use on weekends.

I hope this helps!
