Time Zone Converter
Convert a time between any two zones — with daylight saving handled for you and your chosen zones remembered.
Time zones, without the mental arithmetic
"What's 9 AM New York in Indian time?" is deceptively hard: the answer is 10:30 hours in winter but 9:30 hours in summer, because the US observes daylight saving and India doesn't. This converter picks the correct offset for the exact date you enter — no counting hours, no getting caught out by a DST change. Set your two zones once and they're remembered for next time.
How it works
Conversions run on your browser's built-in IANA time-zone database (the same data operating systems use), so historical and future daylight-saving rules are applied correctly. Enter a time as it reads in the source zone, and you get the matching instant in the target zone, both zones' UTC offsets, and how far apart they are.
FAQ
Does it handle daylight saving time?
Yes — that's the whole point. The offset is computed for the specific date you pick, so a meeting in March lands correctly even if one side just sprang forward.
Why is EST to IST sometimes 10:30 and sometimes 9:30?
The US shifts between EST (UTC−5) and EDT (UTC−4) with daylight saving; India stays on IST (UTC+5:30) year-round. So the gap is 10:30 during US winter and 9:30 during US summer. The converter shows the right one for your date automatically.
Is my data sent anywhere?
No — everything is computed locally in your browser. Nothing is uploaded or stored.
