Atlanta, United States

Atlanta uses Eastern Standard Time (EST) at UTC−5 and EDT at UTC−4. It shares its clock with New York, Miami, and Toronto.

When Hartsfield-Jackson — the world’s busiest airport — opens its first bank of departures at 5 AM, it is 10 AM in London, 2 PM in Dubai, and 7 PM in Tokyo. Connecting flights make timezone awareness critical for millions of travelers.

Home to CNN, Coca-Cola, and Delta Air Lines, Atlanta is a logistics and media powerhouse that coordinates broadcasts and shipments across every continent.
