  • IST is UTC +5:30

  • It does not observe daylight saving time

  • Used across all Indian states and territories

IST is 5 hours and 30 minutes ahead of Coordinated Universal Time (UTC), making it one of the fixed-offset time zones in the world.

Eastern Standard Time (EST) is used in parts of the United States, Canada, and some Caribbean countries.

  • EST is UTC −5:00

  • Used mainly during winter months

Many people confuse EST with EDT, which causes scheduling errors—this is a crucial detail when converting from IST.

This large time gap means most IST work hours fall late night or early morning in EST.
