If you're checking-in to a hotel after midnight you need to book for the date before. For example if you land at 2am on the 13th June, the night of your stay will be the 12th. This is the same rule if you're booking a hotel with parking included.   For parking only products, if you need to drop your car off or pick your car up really early in the morning, you can choose the date and time, down to the hour, that you will be arriving and departing.
