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

ET is currently 1 hour ahead of CST.

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.

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.

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

Is ET ahead of or behind CST right now?

ET is currently 1 hour ahead of CST.

What is the current CST to ET time difference?

Right now the gap is 1 hour — ET is 1 hour ahead of CST.

Does the CST → ET offset change during the year?

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

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).

Does ET observe daylight saving time?

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