you can subtract 2 dates and get the number of days.
sel ( date1 - date2 )
You can also use the Sys_calendar database which is provided by DIP. This Database.table contains the 'Calendar' information for every legal date between Jan 1, 1900 and Dec 31, 2100.
sel yourcolumns, (a.day_of_calendar - b.day_of_calendar ) from yourtable, SYS_CALENDAR.calendar a, SYS_CALENDAR.calendar b where a.calendar_date = yourdate1 b.calendar_date = yourdate2;
