My question however was : isn't there a way to do the equivalent of sysdate - 365 (sql) in unix... Or even simply get a value of the date time as it is actually stored (i read somewhere that it is stored as the number of seconds since 1970). That would help too
That's a blind spot. It's sad to say it, but the only truly portable way to do date math in UNIX is Perl.
GNU date is fantastic if you have it:
...but on AIX or Solaris or anything-but-Linux that's a third-party utility. It's such an obvious feature to put in the date command that people who script in Linux often assume it's everywhere, but it's not. GNU awk has some extended date features too.

So, I have no formal higher education in programming at all and am self taught. I am now wondering what would be considered best practices? Like should I hard code a variable, then compare it to what I want to know or achieve, or should I just put the commands with in the brackets?
