How TimeToZone works
Every number on this site is computed from the IANA time zone database that ships with the platform, at the moment the page is rendered. Nothing is hard-coded: no “EST = UTC−5”, no table of daylight saving dates that goes stale next spring. That matters for the cases most converters get wrong — the three weeks each March when the United States has moved its clocks and Europe has not, the half-hour zones (India UTC+5:30, Nepal UTC+5:45, Newfoundland UTC−3:30), Arizona and Hawaii staying on standard time all year, and the southern hemisphere running summer time in December.
Pages work without JavaScript: the answer sentence, the 24-hour conversion table and the FAQ are all in the HTML. The live clocks fill in once the page loads. There are no accounts, no tracking of your location, and no sign-up.

Time zone converter FAQ
How do I convert a time between two time zones?
Type the time in the first row, then read the answer in the rows below. The converter uses the IANA time zone database, so the daylight saving rules of the date you pick are applied automatically.
What time zone am I in?
Your browser reports it, and the first row of the converter uses it. The What time zone am I in? page shows the full name, abbreviation, UTC offset, IANA id and your next clock change.
Does this converter handle daylight saving time?
Yes. Every conversion is computed for the exact date you choose, including the weeks when the US has changed its clocks and Europe has not, and the southern-hemisphere zones that are on summer time in December.
Is TimeToZone free?
Yes, completely free, with no account and no sign-up. The converter, world clock, meeting planner and every conversion page work without logging in.
