Clear old events from backend

Hello,
I see that old events are automatically cleared from the frontend (Facebook-events page)… but is there a way to clear old events from my backend ?

Of course I can select all and throw it in the trash… but doing that I would throw away future events, and I don’t want that…

If only I could filter it by event date (and not uploading date), I would be able to save future events and throw all the past event to the trash !

Thanks for helping me out with that..
