Time Zone Converter convert time worldwide.

In international meetings, travel, or remote teams, converting times between time zones is an everyday task — and a common source of errors. The reason: UTC offsets are not constant. Most countries switch between summer and winter time, but on different dates and following different rules. The EU switches at the end of March and the end of October, while the US and Canada switch in early March and early November. Some countries such as Japan, China, or the UAE have no daylight saving time at all.

This calculator therefore does not use a self-maintained offset table, but relies on the IANA time zone database, which is built into every modern browser and into Node.js and is continuously updated. As a result, even future changes to daylight saving rules are automatically reflected correctly, without the calculator needing to be maintained.
