Does the difference change during the year?

No. New York and Chicago 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 EST to CST by hand

Take away 1 hour: 3:30 PM EST is 2:30 PM CST.

Going back from CST to EST, do the opposite: the CST to EST page has its own table.

Where the EST and CST working days overlap

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

What EST and CST mean

Eastern Standard Time

EST is UTC−5. The US East Coast and eastern Canada (New York, Washington, Miami, Toronto, Montreal) use it only in winter; from the second Sunday of March to the first Sunday of November they are on EDT, UTC−4. Jamaica, Panama and Cancún keep it all year, and since 2026 so does Manitoba (Winnipeg).

Central Standard Time

CST here is North American Central Standard Time, UTC−6: winter time in Chicago, Houston and Dallas, and all-year time in Mexico City, most of Central America and Saskatchewan. Since 2026 Alberta and the Northwest Territories also stay on UTC−6 all year.

CST can also mean China Standard Time (UTC+8, China) or Cuba Standard Time (UTC−5, Cuba). This page uses Central Standard Time, the meaning people searching for this conversion have in mind. For another one, type the city into the time zone converter.

Questions

How many hours behind EST is CST?
CST is 1 hour behind EST. EST is always UTC−5 and CST is always UTC−6, so this gap is the same on every date.
When is CST on a different date from EST?
From midnight until 1:00 AM EST, CST is still on the previous calendar day. So a time early in the EST day needs the previous date on the CST side.
