The 1.5 mile Charlotte Motor Speedway constructed as a shotgun marriage between Curtis Turner and Bruton Smith was scheduled to run its inaugural World 600 on May 29, 1960. Because of construction delays and lack of readiness for racing (caused largely because of cash flow issues), the race was pushed back until June 19.

At the press conference announcing the delay, NASCAR announced the GN cars would race at Piedmont Interstate Fairgrounds in Spartanburg on June 4th before heading to Charlotte for the multi-day event that became the norm over the years. NASCAR also said Richmond would replace Charlotte on the schedule for May 29th.
As it turns out, the teams instead raced at Piedmont on Saturday the 28th and Orange Speedway in Hillsboro on the 29th. At Hillsboro, Richard Petty won his first pole and Lee won the race.

After Hillsboro, the GN teams DID race at Richmond on June 5th before heading for Charlotte's debut. I'm not clear as to why Spartanburg, Hillsboro and Richmond ended up with different dates than was announced in the press conference - other than the obvious scrambling NASCAR had to do once it became apparently CMS couldn't make the May 29th date.
