John Gregory’s new-look Crawley Town team will begin the Sky Bet League One campaign with a trip to Barnsley on August 9.
The Reds’ first home game of the campaign will be against Swindon Town on Saturday August 16.
The first month will also include trips to much-fancied Sheffield United and MK Dons and a home match with Bradford.
September sees Crawley facing two promoted sides – Rochdale and Fleetwood Town – plus two relegated teams in Doncaster and Yeovil Town.
The Boxing Day fixture will be away to Leyton Orient, with Colchester visiting the Checkatrade.com Stadium two days later.
