About these time zones
JST: Japan Standard Time
Japan Standard Time is UTC+9.
All of Japan, with no daylight saving time.
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.
How the difference changes
Right now EDT is 13 hours behind JST. From 1 November 2026, when US clocks go back, the difference becomes 14 hours. From 14 March 2027, when US clocks go forward, the difference becomes 13 hours.
