The Time Zone Converter lets you instantly translate any date and time into multiple IANA time zones using your browser's built-in Intl.DateTimeFormat API. Select a source zone, pick your date and time, then add as many target zones as you need — from New York to Tokyo to Sydney. Each result shows the UTC offset and a one-click copy button, making it easy to share meeting times or coordinate across continents.
The tool includes 25 carefully chosen IANA time zones covering every major region — including UTC, US time zones (PT, MT, CT, ET), European zones (London, Paris, Moscow), Asia-Pacific (Dubai, Singapore, Tokyo, Sydney), and the Americas (São Paulo, Buenos Aires). You can add or remove any zone from the list.
All conversions use the browser's native Intl.DateTimeFormat API with full IANA zone data, which automatically accounts for Daylight Saving Time transitions. For example, Europe/London shows GMT in winter and BST in summer without any manual adjustment.
Yes. Use the date-and-time picker to enter any date and time — past, present, or future. The converter accurately handles historical DST rules and future scheduled transitions for all supported IANA zones.
Each row has an individual Copy button next to the formatted time. There is also a 'Copy all' button at the top of the results card that copies all converted times as plain text, one zone per line, ready to paste into an email, Slack, or calendar invite.
