About this Time Zone Converter

This converter helps you plan meetings, travel, streaming schedules, or release windows across multiple locations. It uses your browser’s built-in time-zone database, so DST rules and UTC offsets match what devices use in real life. You can add as many target cities or IANA zones as you like, copy a shareable link, and export a CSV for your notes or team.

How to use

  1. Choose the source zone. Type an IANA zone (e.g., America/New_York) or a supported city shortcut like “London” or “Phoenix”.
  2. Pick the time. Leave “Use current time” on, or switch to manual and set a date and time. The tool resolves ambiguous DST moments correctly.
  3. Add targets. Enter another city or zone and click Add. Use Reset to preload common US zones plus London.
  4. Convert. Click Convert to refresh the table. Use “Copy share link” to send your exact setup to someone else, or “Download CSV” to save results.

Understanding the results

Each row shows the local date and time for a target zone, its current UTC offset at that instant, and whether daylight saving time applies. Offsets change over the year in places that observe DST. For example, New York is typically UTC−05:00 in winter and UTC−04:00 in summer. If a time does not exist locally (the “spring forward” gap) or occurs twice (the “fall back” hour), the converter follows the official database rules so you get consistent answers.

FAQ

What is an IANA time zone?

IANA zones look like Region/City, for example Europe/Berlin. They’re the standard identifiers used by modern software and operating systems.

Can I use city names?

Common cities map to their nearest canonical zone. Try “New York”, “Chicago”, “Phoenix”, “London”, “Paris”, “Tokyo”, or “Sydney”.

Why do offsets differ from what I expected?

Offsets depend on the exact date and local laws. This tool calculates the offset at the instant you selected, which may fall on a DST boundary.

Does the tool handle ambiguous times?

Yes. For the hour repeated during the fall DST change, the converter uses a robust two-pass method to resolve the correct UTC instant.

How do I share my setup?

Use Copy share link. The link encodes your source zone, date/time choice, and all targets so anyone can load the same view.
