How to use the converter

Why converting time zones correctly matters

Remote meetings

A 3 PM meeting in New York can be 8 PM in London, 9 PM in Berlin, or 5 AM the next day in Sydney. Getting this wrong wastes time and frustrates participants.

Travel planning

Know exactly when to call home, when your flight lands locally, and how to avoid jet lag scheduling.

Product launches

A simultaneous global launch requires a single UTC reference that everyone converts to their local time.

Broadcast and streaming

Announce go-live times across audiences without ambiguity. See also: countdown timer for release dates.

Daylight Saving Time (DST)

Many countries shift clocks forward in spring and back in autumn. The offset between two zones can change by an hour depending on the date. This converter uses the official IANA time zone database and handles DST automatically — you don't need to remember who shifts when.

For example, the gap between London and New York is normally 5 hours, but briefly 4 hours in mid-March (when the US springs forward a week before the UK) and again in late October.

Frequently asked questions

Does the converter handle daylight saving time?
Yes. It uses the browser's built-in IANA time zone data, which stays current with DST rules worldwide.
Can I convert a future date?
Yes. Pick any date — the tool applies the correct DST offset for that specific date.
Why are some times off by one hour near March or November?
That's DST transitions. Different regions shift on different weekends, so the gap changes for a week or two.
What's the difference between GMT and UTC?
For most practical purposes they're identical. UTC is the modern scientific standard; GMT is its informal name still used in the UK and broadcasts.
