How to use the time zone converter
- Convert a time. Enter a date and time, pick the source zone and the target zone — the converted time appears instantly with both UTC offsets.
- Plan a meeting. Set the meeting time, then add the zones your attendees are in. Each row shows the local time side by side.
- Glance at the world clock. The strip shows the current time in major cities, updating live.
- Mind daylight saving. Converting the same clock time in January and July can differ by an hour — the converter accounts for it automatically.
Frequently asked questions
How are daylight-saving changes handled?
Automatically. Offsets are computed for the exact date and time you enter using your browser's built-in time zone database, so EDT versus EST and similar shifts are correct.
Why did my converted time shift by an hour compared to last month?
One of the zones entered or left daylight-saving time. The converter uses the offset in force on the date you entered, which is the correct behavior.
Where do the time zone offsets come from?
Your browser's Intl data — the same database operating systems use. No network requests are needed and it works offline.
Which time zones are included?
Every IANA time zone your browser knows, with major cities as curated defaults in the pickers.
Is my data sent anywhere?
No. All conversions happen in your browser; nothing is sent to a server or stored, except your meeting-planner zone list, which stays in your own browser.
