The car hire companies at Girona airport are open from 08:00 - 23:45 from Monday to Sunday. There is a few minutes variation between each company, but between these times there will always be at least one office open.
Opening hours can change, so I advise you to check directly with the car hire company before you travel, especially if you will be arriving during the night or during the winter season from October to May.

You'll also find 2 companies on the approach road to the airport from the A7 motorway (after the tolls). They offer a shuttle to take you between the airport and their offices. It's worth checking out their prices as they can be very reasonable.
