Convert a date and time between major world cities — IST, UTC, EST, GMT, and more — in your browser.
Why this matters
If you've ever scheduled a call with someone in the US or UK and gotten the time wrong by 5–12 hours, you already know why a time zone converter matters. India (IST) is UTC+5:30, which means most of Europe is 4–5 hours behind and the US is 9.5–12.5 hours behind. Get it wrong and you wake someone up at 3 AM — or show up to your own meeting 10 hours late.
This tool handles all the offsets for you, including the awkward 30- and 45-minute ones (Nepal, India, parts of Australia). Pick a city, pick another city, and you instantly see the converted time — no mental math, no DST mistakes.
Best uses: scheduling remote work calls, coordinating with overseas clients, planning travel, checking if your favourite show airs yet in your time zone, and not texting your parents at 6 AM their time on Thanksgiving.

Meeting times across countries
Pick a source time zone (default India IST), enter the local date and time, and see the equivalent in another city. Useful for remote interviews, client calls, and webinars spanning the US, Europe, Middle East, and APAC.
How conversion works
Conversion uses your browser’s Intl time-zone data — no account and no server. Daylight-saving rules for zones like New York and London are applied automatically by the runtime.
India tip
India does not observe daylight saving. When you convert IST to US Eastern or UK time, the offset can change with their seasons — always double-check around March and November.
