About these time zones
CST: Central Standard Time
Central Standard Time is UTC−6. CST is also used for China Standard Time (UTC+8) and Cuba Standard Time (UTC−5). This page converts North American Central Time.
Texas, Illinois, Minnesota, Louisiana and most of the Midwest and South, plus Manitoba in Canada. Saskatchewan and most of Mexico stay on CST all year. CT is the short form for the whole zone.
Most places on Central Time are on CDT (UTC−5) right now, not CST. People still say "CST" all year, so the times on this page follow the clocks and show CDT until 1 November 2026.
EDT: Eastern Daylight Time
Eastern Daylight Time is UTC−4.
New York, Florida, Georgia, the Carolinas, Ohio, Michigan and the rest of the East Coast, plus Ontario and Quebec, from March to November.
How the difference changes
Both zones change their clocks on the same dates (next on 1 November 2026), so the difference stays 1 hour all year.
