The Chicago to New York Time Difference
Chicago (Central Time) is always one hour behind New York (Eastern Time). This gap is stable year-round because both regions observe Daylight Saving Time (DST) simultaneously. Central Time is UTC-6 (CST) in winter and UTC-5 (CDT) in summer; Eastern Time is UTC-5 (EST) in winter and UTC-4 (EDT) in summer. When DST starts in March, both clocks spring forward together, preserving the one-hour difference.
