What can I search?

Enter a country name, city, IANA timezone or two-letter country code. You do not need to know the country code—typing India automatically searches IN.

Choose an example above or enter any country name, city or timezone.

About the Timezone Database Lookup

Timezone Database Lookup searches a versioned import of the public-domain IANA Time Zone Database instead of contacting an upstream provider for each request.

Results include canonical zone identifiers, country mappings, coordinates, current local time and offset, plus the source release metadata.

Key features

  • Canonical IANA timezone identifiers
  • Country-name, country-code and city search
  • Current local time and UTC offset
  • Version and source metadata
  • No per-request upstream provider

How to use

  1. 1Enter a country name such as India, a city such as Kolkata, an IANA zone such as Asia/Kolkata, or a two-letter country code.
  2. 2You can also choose one of the example searches; knowing a country code is not required.
  3. 3Select Search timezones.
  4. 4Review the canonical identifier, country mapping, current offset and dataset version.

Examples

Find India's canonical timezone
Input: IN or Kolkata
Output: Asia/Kolkata with its current offset and release metadata

Frequently asked questions

Is the timezone data live?
No. Zone definitions come from a pinned IANA tzdata release. Current time and offset are calculated when you run the lookup.
What license applies?
The IANA Time Zone Database data used by this lookup is released to the Public Domain.
Why can timezone rules change?
Governments can change UTC offsets and daylight-saving rules, so the source release is shown with every result.
