The Time Zone API provides time zone data, including UTC and daylight savings offsets, for specific locations based on latitude/longitude and timestamp.
You can use the API to display localized time zone names, offsets, and enhance time-based data in your applications.
The API accepts HTTPS requests with location and timestamp parameters and returns data in JSON or XML format.
Client libraries are available in Java, Python, Go, and Node.js for easy integration into your projects.

The Time Zone API is a service that accepts an HTTP request of latitude/longitude coordinates and a chosen date and time. It returns the time zone data for the location, including offsets for UTC and daylight savings time.

Why use the Time Zone API

With the Time Zone API, you can develop applications that provide the time zone ID and name for dates and times at specific locations on a map. For example, you can show the following time zone data:

Localized time zone names for map locations from the Google Maps Platform.
Time zone offsets from UTC and for daylight savings.

Time zone data can be particularly useful when you want to have your website or app display time-based data relevant to your users.

What you can do with the Time Zone API

With the Time Zone API, you can request the time zone for locations on the surface of the earth, with the time offset from UTC and for daylight savings time for each of those locations.

How the Time Zone API works

The Time Zone API accepts an HTTPS request of latitude/longitude coordinates, the desired date and time as a timestamp, and optionally, a language code. It returns data in the format specified by the request. The following example shows a request for Nevada, USA, with a requested output in JSON.

    ?location=39.6034810%2C-119.6822510
    &timestamp=1733428634
