Does Debian have a "nag" tool?

[Richard Owlett <rowlett@cloud85.net>]

Just missed girlfriend's birthday by 6 weeks :{
[just sent a 'mea culpa' email.]
Is there a better tool than "cron"?

Just looked at its manpage.
I'm looking for something slightly different.

Independent of when I turn on or first do something after midnight on a 
specific date I want a reminder to be displayed unless I have taken a 
specific action.

As:
 1. I've known her for > 30 years.
 2. I'm a _senior_ citizen.
 3. She is a decade younger.
I am about to receive just retribution.
  [She'll claim I'm forgiven due to senility.]

Wish to prevent such a response next year ;/

TIA
