What is IST (Indian Standard Time)?
IST is UTC+5:30 and is observed throughout India. India does not observe daylight saving time, so IST remains constant year-round while other zones shift.
Why doesn't India have daylight saving time?
India spans a relatively narrow longitudinal range, so a single time zone works well. Daylight saving would create minimal benefit while causing significant disruption to scheduling and systems.
What is the best time for India-US meetings?
For India-East Coast US: 7:00-9:30 PM IST (9:30 AM-12:00 PM EST). For India-West Coast US: 6:30-8:30 AM IST (6:00-8:00 PM PST previous day). Use our Meeting Planner to find the optimal slot.
How do I handle daylight saving time (DST) changes?
Our converter uses the IANA time zone database which automatically accounts for DST transitions. Just select the city (e.g., "New York") and the tool handles EST/EDT switches automatically.
