Frequently asked questions
What if my pair is not listed?
Use the converter at the top of this page. It covers 224 cities, countries and time zones, not just the pairs with their own page. To compare three or more places at once, use the meeting planner on the home page.
Which converters are used most?
IST to UTC, UTC to IST, IST to EST and EST to IST get the most visits, followed by IST to PST and UTC to EST. Most of our visitors are working between India and the US or UK.
Do the converters handle daylight saving time?
Yes. Every converter uses the IANA time zone database built into your browser and applies the rules in force on the date you pick, so the weeks when only one side has changed its clocks come out right.
Why does a pair show EST in winter and EDT in summer?
The US East Coast uses Eastern Standard Time (EST, UTC-5) from November to March and Eastern Daylight Time (EDT, UTC-4) from March to November. The page name uses the familiar abbreviation, but the times shown always use the one actually in force.
