It seems like there would be a decent way to do this. I have support agreements for all my accounts. I want to set up contracts for each, set an end date and have alerts or events happen when the end date has been reached. I noticed a "Days to Expiry" field when I view contracts, but my workflow conditions dont show this field for some reason.

I feel this has to be possible, but documentation has been a dead end. I know I must be missing something so simple.
