Narrative:

After taxi to runway 27, we were delayed waiting for out takeoff weight and balance. We were cleared onto runway 27 and had to make a left turn to back taxi. Captain was lining up the aircraft I was reading the complete before takeoff checklist. Since we were delayed from completing any of the items on the list until we had our weight and balance. This distraction caused me to be head down the whole time while the captain maneuvered the aircraft into position. We had been cleared for takeoff this whole time so as soon as I completed the checklist the captain gave me the airplane and we commenced the takeoff roll. Almost immediately the tower told us to abort our takeoff because we were on the wrong runway. Runway 23 instead of 27. Causes of this incident are numerous. One was the close proximity and layout of the 2 runways is confusing, I wasn't able to back up my captain due to the combination of being cleared for takeoff, running the complete checklist, and running behind schedule, as well as a short night rest on a trip scheduled as an all night on duty with barely 4 hours sleep in between segments because of delays. The tower was also questioning us to see if we would be able to make our departure clearance slot. The combination of fatigue, the hurried pace of completing checklists and trying to make an edc time, and the close proximity of the 2 runways, all contributed to this incident.
