The Fun Day has been a focal point of pre-seasons as it allows the fans to meet and greet new signings and collect autographs.
This season's Open Day will take place on Sunday 29th July 2007.
Meanwhile The Reds will host Premiership Wigan Athletic in a pre-season friendly for the second year in a row.
Last year the game took place on Tuesday 1st August with The Reds narrowly losing 2-1.
This year the Latics will make the trip to Oakwell on the same Tuesday but the date this year is 31st July. The Reds were very nearly facing Wigan in league action but The Latics produced a dramatic last day win to preserve their Premiership status.
