ET to CST Time — Convert Eastern Time (US) to Central Standard Time (US)

CST is currently 1 hour behind ET.

On Clockjumper, ET refers to the Eastern Time zone of the United States and Canada. ET is an umbrella name rather than a fixed offset: it means EST (UTC−5) in winter and EDT (UTC−4) in summer, and these pages show whichever is currently in force.

On Clockjumper, CST refers to US Central Standard Time (UTC−6). The same three letters are also used for China Standard Time (UTC+8) and Cuba Standard Time (UTC−5) — check the city or UTC offset to be sure which is meant.

The ET → CST offset stays constant across the year — neither zone shifts for daylight saving in a way that changes this gap.

CST is currently 1 hour behind ET.

What is the current ET to CST time difference?

Right now the gap is 1 hour — CST is 1 hour behind ET.

Does the ET → CST offset change during the year?

No. Neither Eastern Time (US) nor Central Standard Time (US) shifts for daylight saving in a way that changes this offset — the gap is the same all year.

Does ET observe daylight saving time?

Yes — Eastern Time (US) observes DST, so its UTC offset shifts by 1 hour between winter and summer.

Does CST observe daylight saving time?

CST is itself the standard-time form. Central Standard Time (US) is in force at UTC-6 through the winter months; outside that window the same zone is on CDT (UTC-5).
