Trigger on a date diff

[high-t]

Hi.

I have a system which I'm querying for a date. This date is always a future date.
I need to set a trigger that will fire if that date is 20 days or less from today.

With that, there are two problems:

1. The date is being returned to the item as a string object, formatted DD/MM/YYYY
2. How can I calculate the difference in days between today and the future date returned from the system?

Thank you in advance!

Amit.
