Isn't that just to take the first 2 bytes for each field, subtract and get the difference? or also you can use the intrinsic functions for DATEs.

Also, you can take the help of below link,

You need to CLEARLY define the rules -- is a difference of 1 month and 1 day to be considered 1 month, or 2 months? how about 1 month and 29 days? how about February 28 to March 1? how about February 28 to March 1 in a leap year?

If I had to do this, depending upon the exact requirement, I would probably convert both dates to days using the intrinsic function, subtract, and divide the difference by 30 with rounding. No, that would not be exact but unless the requirement is more clearly stated. in most (but not all) cases that would be close enough.

For precision, you have to iterate from the earlier date to the later date, handling February and December / January along the way.

Most sites have date handling routines LONG established and generally if such routines are available at your site -- USE THEM. Yes, they are custom to each site, but they will provide what the site requires.

Full (and correct) answer depends on how your dates are stored and how they are accessed.
Just as an example, if you are reading your data from a DB2 table, you could just select the interesting rows:
Code:
SELECT  ....
FROM    ...
WHERE   MATURATION_DATE < (CURRENT DATE - 3 MONTH)
