time tool
Timezone Converter
Enter a date and timezone such as America/New_York to format the equivalent local time.
Paste data here. It stays in your browser.
Copy-ready result appears here.
How it works
- Reads the first line as the date.
- Reads the second line as an IANA timezone.
- Formats with Intl.DateTimeFormat.
Common use cases
- Schedule meetings.
- Check market opens.
- Plan maintenance windows.
Code example
new Intl.DateTimeFormat('en-US', { timeZone: 'America/New_York' }).format(new Date()) Use IANA timezone names
Names such as America/New_York, Europe/London, and Asia/Shanghai are safer than abbreviations like EST or CST, which can mean different things.
Daylight saving time
The browser Intl API accounts for timezone rules available in the runtime. Still, important scheduling decisions should be checked against the official calendar for the region.
