Comparing dates

I am new to DB2, and I want to compare two dates, i.e., posted date with the expiry date. If posted date is more than seven days old, I need to archive that topic. Or if the current date is greater than expiry date, I need to archive that topic. How can I do the date comparisons in DB2? Is there any DB2-specific function for date comparisons?
