Bold rows fall inside office hours (9:00 to 17:00) on both sides. The dot marks the current CT hour.

Does the difference change during the year?

No. Chicago and New York both change their clocks, on the same dates and in the same direction, so the gap of 1 hour holds all year.

On the change nights themselves the two sides do not switch at the same instant. Each changes at its own local time, so for 1 hour in the early hours the gap between the local clocks is different: 2 h on Mar 14 and 0 h on Nov 7, 2027. That matters only for events scheduled in the middle of the night.

Converting CT to ET by hand

Add 1 hour: 3:30 PM CT is 4:30 PM ET.

Going back from ET to CT, do the opposite: the ET to CT page has its own table.

Where the CT and ET working days overlap

Two 9:00–17:00 days share 7 hours: 9:00 AM to 4:00 PM CT, which is 10:00 AM to 5:00 PM ET.

What CT and ET mean

Central Time

CT means the current time in the US Central zone (Chicago, Houston, Dallas, Minneapolis): CST (UTC−6) in winter and CDT (UTC−5) in summer.

Eastern Time

ET means whatever the clocks on the US East Coast show: EST (UTC−5) in winter and EDT (UTC−4) from the second Sunday of March to the first Sunday of November.

Questions

How many hours ahead of CT is ET?
ET is 1 hour ahead of CT all year. Both sides change their clocks on the same dates, so the gap does not move.
When is ET on a different date from CT?
From 11:00 PM CT to midnight, ET is already on the next calendar day. So a time late in the CT day needs the next date on the ET side, and the reverse holds when you convert back.
