Central Time to Eastern Time Converter
Eastern Time is always exactly one hour ahead of Central Time. Enter a Central time and date, and this converter shows the matching Eastern time, correctly labeled as CST or CDT converting to EST or EDT depending on daylight saving. No math, no guessing about the March and November clock changes.
Eastern is always 1 hour ahead of Central, in winter and summer.
How to use
- Pick the date for the conversion.
- Enter the Central time (Chicago time).
- Click Convert to Eastern Time.
- Read the Eastern result, labeled EST or EDT depending on the date.
The one-hour rule, explained
The conversion could not be simpler: Eastern = Central + 1 hour. 9:00 AM in Chicago is 10:00 AM in New York. 5:30 PM in Dallas is 6:30 PM in Atlanta. 11:45 PM in New Orleans is 12:45 AM the next day in Miami, so watch the date near midnight.
The rule survives daylight saving because both zones move together. In winter you are converting CST (UTC-6) to EST (UTC-5); in summer CDT (UTC-5) to EDT (UTC-4). Either way the arithmetic is plus one hour.
Daylight saving dates to remember
In the United States, daylight saving time starts on the second Sunday in March and ends on the first Sunday in November. For 2026 that means spring forward on March 8 and fall back on November 1.
Because both zones share the schedule, you never need to think about it for a Central to Eastern conversion. It only matters when converting to zones with different schedules (like Europe, which changes on different Sundays) or zones without daylight saving at all.
Frequently asked questions
Is Eastern always exactly one hour ahead of Central?
Yes. Central and Eastern are adjacent US zones, so Eastern is always one hour ahead. Add one hour to any Central time to get Eastern time. This never changes, in any month.
What is the difference between CST and CDT?
CST (Central Standard Time, UTC-6) runs from the first Sunday in November to the second Sunday in March. CDT (Central Daylight Time, UTC-5) runs the rest of the year. Your clock reads the same either way; only the label and the UTC offset change.
What is the difference between EST and EDT?
EST (Eastern Standard Time, UTC-5) is the winter label; EDT (Eastern Daylight Time, UTC-4) is the summer label. The converter picks the right one for your date automatically.
Does the one-hour rule still work during daylight saving?
Yes. Both zones observe daylight saving over the same period (second Sunday in March to first Sunday in November), so they shift together and the gap stays exactly one hour. 2:00 PM CDT is 3:00 PM EDT.
When do the clocks change in 2026?
Daylight saving starts Sunday, March 8, 2026 (clocks forward) and ends Sunday, November 1, 2026 (clocks back). Both Central and Eastern follow this US schedule.
Do all Central Time places observe daylight saving?
Most do, but not all. Most of Arizona stays on standard time year-round, and parts of Mexico near the US border follow their own rules. If your Central location is an exception, convert from its exact city zone instead.
