About the time in Charleston
Charleston runs on America/New_York, which puts the city UTC −4 from Coordinated Universal Time right now. The clock at the top of this page is not copied from your device: it is anchored to our reference timestamp and re-rendered every second against the IANA time zone database, so it stays right even when a laptop or phone has quietly drifted.
Charleston is on daylight saving time at the moment, which is why the offset reads UTC −4 instead of its winter value. Clocks go back on 1 November 2026, and anything scheduled across that date shifts by an hour.
The zone identifier America/New_York is the value you want in code, calendars and travel systems. Abbreviations change with the season, but America/New_York keeps pointing at New York time whatever the date, which is why every timestamp on this page is built from it.
