About IST and EST

India Standard Time (IST, UTC+5:30) covers Mumbai, Delhi, Bengaluru and Chennai, and fixed at UTC+5:30 all year (India has no daylight saving). Eastern Time (EST, UTC−5) covers New York, Toronto, Miami and Atlanta, and observes daylight saving (EST in winter, EDT in summer).

Because Eastern Time observes daylight saving while the other side doesn't, the difference shifts by one hour between winter and summer — the table below shows both.
