Frequently Asked Questions
What is the time difference between IST and EDT?
During standard time, Eastern Daylight Time is 9.5 hours behind Indian Standard Time.
Does India observe Daylight Saving Time (DST)?
India does not observe Daylight Saving Time and has not done so since 1945. IST remains fixed at UTC+5:30 every day of the year, meaning the offset between India and any DST-observing country shifts by one hour twice annually when those countries change their clocks.
Why does IST have a 30-minute offset?
India chose the 82.5° East meridian — which passes through Mirzapur in Uttar Pradesh — as its central reference longitude, as it bisects the subcontinent geographically. That meridian sits exactly 5 hours and 30 minutes ahead of the Prime Meridian in Greenwich, producing the UTC+5:30 offset that has defined IST since 1906.
When does EDT start and end?
EDT begins on the second Sunday in March at 02:00 local time, when clocks spring forward one hour from EST (UTC-5) to EDT (UTC-4). It ends on the first Sunday in November at 02:00 local time, when clocks fall back to EST. In 2026, EDT runs from March 8 through November 1.
Is EDT the same as EST?
EDT and EST are two phases of the same Eastern Time zone, not two separate zones. EST (Eastern Standard Time) is the winter offset at UTC-5, observed from early November through mid-March. EDT (Eastern Daylight Time) is the summer offset at UTC-4, active during Daylight Saving Time — meaning New York and Toronto run one hour ahead of their winter clock for roughly eight months of every year.
