What's the current time difference between KST and Chicago?

Right now, Chicago (Chicago) is −14h relative to KST (KST · Korea Standard Time). The number is live and reflects the current daylight-saving status of both zones.

Does this converter account for daylight saving time?

Yes. The math is done against IANA's tz database via Intl.DateTimeFormat, so DST shifts in either zone show up immediately at the transition. Around DST boundaries the conversion can move by an hour from one week to the next — this page always reflects the current rule.

Why does the TO column sometimes show "+1d" or "−1d"?

When the KST hour lands on a different calendar day in Chicago, we flag it so you don't accidentally schedule a meeting on the wrong date. KST 11 PM is often the next day in eastern-hemisphere zones, for example.
