Timezone Converter

Pick a date and time in your local timezone to see the equivalent time around the world.

What this tool does

This tool takes a date and time in your browser's local timezone and converts it to the equivalent moment in over a dozen major world timezones at once — from Los Angeles to Auckland — using the browser's built-in Intl internationalization API, which carries accurate timezone and daylight-saving-time rules. Everything is calculated locally; nothing is sent to a server.

Example use case

Scheduling a meeting across a distributed team, checking whether it's a reasonable hour to call a client overseas, or figuring out when a live event airs in your own timezone all require converting a single point in time across multiple zones at once, which is tedious to do by hand and easy to get wrong around daylight saving transitions.

Daylight saving time

Because this tool uses the Intl API's real timezone database rather than fixed UTC offsets, it automatically accounts for daylight saving time in each region — so a time converted in July and the same time converted in January may show different offsets from UTC for timezones that observe DST.
