Why Use Our Tool
Our Time Zone Converter uses your browser's built-in Intl.DateTimeFormat API — the same system your device uses to display times. This means conversions are automatically accurate, including daylight saving time adjustments, which change by region and season and are notoriously tricky to handle manually.
Features
All IANA time zones are supported — over 400 zones covering every country, territory, and major city worldwide. The tool correctly handles daylight saving time, historical timezone changes, and half-hour offsets (used by India, Iran, Afghanistan, and several other countries). No external API calls are required; everything runs in your browser.
Accurate Time Zone Information
Time zones are more complex than UTC offsets suggest. Many regions observe daylight saving time (DST) for part of the year, shifting clocks forward in spring and backward in autumn. The Intl API handles all DST transitions automatically based on your browser's timezone database, which is regularly updated to reflect changes in timezone laws around the world.
