The most common EST-to-CST conversion in practice is coordinating between an East Coast office and a Chicago or Texas team.
Why the gap is always exactly 1 hour
The US Eastern and Central zones both follow the same federal daylight saving schedule — clocks change on the second Sunday of March and the first Sunday of November, the same day in both zones. Because they shift together, the difference between them stays locked at 1 hour throughout the year. There is no transition-week wobble like you get between countries that change their clocks on different dates.
EST vs EDT, CST vs CDT
The "S" versions (EST, CST) are the standard-time winter names; the "D" versions (EDT, CDT) are the daylight-time summer names. Eastern runs at UTC-5 in winter and UTC-4 in summer; Central runs at UTC-6 in winter and UTC-5 in summer. Most people say "EST" and "CST" loosely to mean Eastern and Central Time all year. Whatever the season, Eastern stays exactly 1 hour ahead of Central.
