Do you mean this:
Or this :
Or This Extension :
See Doing an action at a specified date or every week

I think he/she means running in the background
While you generally can't run applications in the background, there are extensions to do things like receive push notifications and, with the most recent release, extensions can now run background services. It might be possible to do what you want but without more details about the flow of the information it's hard to give specific advice.
