Our free CST to EST converter instantly translates Central Time across Chicago, Dallas, Houston, and Austin into Eastern Time for New York, Boston, Atlanta, and Washington DC. Whether you're scheduling a meeting between the Midwest and the East Coast, this tool removes the mental math and shows you the exact local time on both sides.
Eastern Standard Time (EST) is always exactly 1 hour ahead of Central Standard Time (CST). This fixed 1-hour gap never changes: (Time-zone offsets follow the IANA Time Zone Database, the authoritative source operating systems use for time-zone rules.)
With only a 1-hour difference, nearly the entire business day overlaps. For example, 9:00 AM CST = 10:00 AM EST — both sides are in their morning. Simply add 1 hour to any Central time, and you have the Eastern time. Both regions share almost the full working day, making scheduling straightforward.
