Asunto: Dates and length of period


Dear all,

I have a database with 2 data-variables: date1 and date2. I would like to calculate the length of the period in days between date1 and date2. The number of days should be a new variable. e.g.: the length of the period between date1 and date2 for respondent 1 is 35 days. This is the simplified database:

data list free / resp (f2.0) date1 (edate8) date2 (edate8).

begin data

1 06.07.03 10.08.03

2 25.07.03 14.08.03

3 18.05.03 23.09.03

4 01.06.03 05.07.03

end data.

Can anyone help me out? Many thanks in advance!

Paul Hover
