Time Zone Converter

The Time Zone Converter is a free online time zone converter that takes a date and time in one city and shows the exact corresponding time in another, across 40+ major time zones from Los Angeles to Auckland. It's the easy way to schedule calls, webinars, live streams and deadlines with colleagues, clients or family spread across different countries without doing the timezone conversion math by hand.

A common use case is converting a meeting time from US Eastern time to India — an est to ist conversion — or checking what a UTC-stamped log timestamp or API deadline means in your local time with a utc converter. Because the tool covers 40+ zones by city name rather than raw offsets, you can pick 'New York' or 'Mumbai' directly instead of remembering whether a given offset is currently UTC−5 or UTC−4.

Daylight saving time is handled automatically for the specific date you pick, not just the current date — so a meeting scheduled for a date in July converts correctly using Eastern Daylight Time (UTC−4), while the same clock time in January correctly resolves to Eastern Standard Time (UTC−5). The tool also displays each zone's current UTC offset and the number of hours the two locations are apart, which is useful context when the converted time lands on a different calendar day than you expected.

Conversions run entirely on your device using the browser's built-in IANA time zone database, which is kept current with the latest DST and offset rule changes for every region — nothing about your schedule is uploaded or stored anywhere. That also means the tool keeps working correctly years from now, since it always reflects the DST rules in effect for whatever date you select rather than a hardcoded snapshot.
