Central Time (CST/CDT) · Nashville · East TN uses Eastern Time
Tennessee is split between CT (west and middle) and ET (east). Nashville (country music capital) and Memphis (blues/rock birthplace) are on CT, while Knoxville and Chattanooga are on ET. The boundary roughly follows the Cumberland Plateau.
Nashville is the fastest-growing major US city and the undisputed capital of country music. The Grand Ole Opry broadcasts live every weekend on CT. Nashville has also become a major healthcare, tech, and tourism hub — HCA Healthcare ($60B+) and AllianceBernstein are headquartered here.
Memphis is where Elvis Presley lived at Graceland, where B.B. King played on Beale Street, and where FedEx operates the world's largest cargo hub at Memphis International Airport. FedEx's overnight delivery guarantee is built around CT sorting times.
