What is a time zone converter?
A time zone converter shows what a clock time in one place equals in another part of the world. Each zone has an offset from Coordinated Universal Time (UTC) — for example New York is UTC−5 in winter and London is UTC+0 — and the tool applies the difference between the two zones.
How it works
The converter changes your chosen time to UTC using the source zone's offset, then adds the destination zone's offset. Many regions use daylight saving time (DST) for part of the year, which shifts the offset by one hour, so the converter uses the rule in effect on the date you pick.

How to use
Enter the date and time you want to convert. Choose the "from" time zone (defaults to your local zone) and the "to" zone. The converted time appears instantly with the weekday and date.
Type to filter the time zone list. Zones are IANA names like Europe/London or America/New_York — pick the city closest to you for accurate DST.
The conversion uses your browser's built-in time zone data. Nothing is sent over the network.
