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

CST is currently 1 hour behind EST.

On Clockjumper, EST refers to Eastern Standard Time in the United States (UTC−5). The US East Coast observes EST in winter and switches to EDT (UTC−4) during daylight saving time.

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