Hi Rady, I used a kind of hack for doing that:
I first used a program rule to copy the event_date into a new data element of the program stage (so, yup, the date is kind of duplicated in the stage). However then I could create a program rule variable to fetch this date I wanted, and compare it with another one. Hope this could help.
