Some thouths for 6 month's from now:

Whether you save it as a separate field or simply use the 6 month add
routine, don't forget that you will most probably need to ALWAYS do a
range search on the report date for your report.

Today is Thursday. But 6 months from now might NOT be a normal work
day or it might end up on a Holiday. What date will you get adding 6
months to Dec 31st? During a leap year? During a non-leap year?
