FAQ
What's the difference between IST and EST?
IST is 10.5 hours ahead of EST (New York winter); 9.5 hours ahead during daylight saving (EDT, summer). This tool handles DST automatically — so it's more accurate than manually adding/subtracting.
Is daylight saving time (DST) handled?
Yes — the browser's timezone database is used, which knows DST rules. The summer-winter difference in US/Europe zones adjusts automatically.
How do I use this to plan a meeting time?
Enter your proposed time in IST, choose the client's zone in To — their local time appears. If it falls within 9 AM–6 PM, set the meeting.
Why doesn't India observe DST?
India is close to the equator, so the seasonal difference in daylight is small — DST offers no benefit. IST stays UTC+5:30 all year.
