Getting the difference between two dates using sc_dif_date

Scriptcase provides the macro sc_date_dif(date1, date1 format, date2, date2 format) to calculate difference between dates in number of days. 

date1 - Value or variable containing the first date.
date1 format - Value or variable containing the format of date1.
date2 - Value or variable containing the second date.
date2 format - Value or variable containing the format of date2.

Example 1:

{days} = sc_date_dif({date1}, "yyyy-mm-dd", {date2}, "yyyy-mm-dd");

Example 2:

{days} = sc_date_dif("2006-09-01", "aaaa-mm-dd", "19/01/2007", "dd/mm/aaaa");
