About these time zones
IST: India Standard Time
India Standard Time is UTC+5:30. IST is also used for Irish Standard Time (UTC+1, Ireland's summer time) and Israel Standard Time (UTC+2). This page converts India Standard Time.
All of India, with no daylight saving time. Sri Lanka uses the same offset.
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 9 hours 30 minutes behind IST. From 1 November 2026, when US clocks go back, the difference becomes 10 hours 30 minutes. From 14 March 2027, when US clocks go forward, the difference becomes 9 hours 30 minutes.
