Frequently asked questions

Common questions about the Time Zone Converter.

How does the time zone converter work?

Enter a date and time, then pick a source zone and a target zone — it shows the equivalent local time in the target zone instantly.

Is there a live current-time mode?

Yes. A live mode shows the current time side by side across the zones you choose, handy for coordinating calls in real time.

What is the time difference between IST and EST?

India Standard Time (IST) is UTC+5:30 and US Eastern Standard Time (EST) is UTC−5, a difference of 10 hours 30 minutes (10:30 in EST is 21:00 in IST).

Why is scheduling across time zones so error-prone?

Zones differ by odd offsets (some by 30 or 45 minutes) and daylight-saving shifts move the gap a few times a year, so a fixed “X hours ahead” rule quietly breaks.
