Time Zone Converter
Enter a date and time in one time zone to see the equivalent local time in another.
Overview
Time zone offsets aren't fixed — daylight saving time shifts most zones by an hour for part of the year, and the shift happens on different dates in different countries. This tool reads each zone's actual offset for the date you enter, using the browser's built-in time zone database, so a conversion in July and the same conversion in January can correctly give different results for a zone that observes daylight saving.
Examples
New York to India
2026-08-15 09:00 AM, America/New_York → Asia/Kolkata

How It Works
- Enter the date and time.
- Choose the source time zone.
- Choose the target time zone.
- The converted local date and time appear instantly, along with both zones' UTC offsets for that date.
Use Cases
Scheduling meetings
Find the local time for a meeting scheduled in a colleague's or client's time zone.
Travel planning
Work out what time it will be at your destination when you land.
Tips
- This tool is a wall-clock converter — it doesn't need to know your own device's time zone, since you specify both the source and target zones directly.
FAQ
No. The conversion runs entirely in your browser using the JavaScript Intl time zone database.
Yes, for nearly all dates — the offset is computed for the specific date you enter, not a fixed year-round value. Times that fall exactly within a DST transition hour (the single "skipped" or "repeated" hour on the transition day) are a known edge case for this style of calculation.
