Dale will launch their new campaign at home against Posh for the second successive season having lost 1-0 at Spotland in August last year.
“Playing Peterborough again on the first day of the season will give us a good marker to see what has happened in the last 12 months,” assistant manager Beech told the club’s official website.
“But it will be a different time and a different opportunity. We’re grateful to get a home game and we’re looking forward to the start of the season.
“We won’t be surprised by League One, like I think we were when we started playing the first few games of the season last year – our performances were good but we lacked results.
“Everything prior to the first game of the season is preparation and a lot of focus goes on that, but of course there are another 45 league games after that.”
