About these time zones
EST: Eastern Standard Time
Eastern Standard Time is UTC−5.
New York, Florida, Georgia, the Carolinas, Ohio, Michigan and the rest of the East Coast, plus Ontario and Quebec in Canada. Panama, Jamaica and Cancún stay on EST all year. ET is the short form for the whole zone.
Most places on Eastern Time are on EDT (UTC−4) right now, not EST. People still say "EST" all year, so the times on this page follow the clocks and show EDT until 1 November 2026.
CDT: Central Daylight Time
Central Daylight Time is UTC−5. CDT is also used for Cuba Daylight Time (UTC−4). This page converts North American Central Time.
Texas, Illinois, Minnesota, Louisiana and most of the Midwest and South, plus Manitoba, from March to November. Saskatchewan and most of Mexico don't switch to CDT.
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.
