Frequently asked questions
What is CST to EST time difference?
On paper, CST is UTC −6 and EST is UTC −5. In practice the two abbreviations are rarely observed at the same time of year — right now Chicago is on CDT and New York is on EDT, and the live clock and 24-hour table on this page follow those real wall clocks, which is what you want for scheduling.
Does CST change for daylight saving?
CST itself is the standard (non-DST) form. The clock that uses CST switches to a daylight-saving variant in summer.
What time is 9am CST in EST?
9:00 AM CDT ≈ 10:00 AM EST.
