Get Started

The Time Zone API provides time offset data for locations on the surface of the earth. You request the time zone information for a specific latitude/longitude pair and date. The API returns the name of that time zone, the time offset from UTC, and the daylight savings offset.

Sample request and response

You access the Time Zone API through an HTTPS interface, with requests constructed as a URL string, using latitude/longitude coordinates to specify the location, a timestamp to specify the date, and your API key.

Note: You must submit requests via https, not http.

The following example requests the time zone data for Washington, DC, USA, on March 15, 2016, in JSON format:

https://maps.googleapis.com/maps/api/timezone/json?location=38.908133,-77.047119&timestamp=1458000000&key=YOUR_API_KEY

You can test this by entering the URL into your web browser (be sure to replace ‘YOUR_API_KEY’ with your actual API key). The response includes the time zone data for the specified location and date (timestamp).

View the developer's guide for more information about building request URLs and available parameters and understanding the response.

Below is a sample response, in JSON:

{
   "dstOffset" : 3600,
   "rawOffset" : -18000,
   "status" : "OK",
   "timeZoneId" : "America/New_York",
   "timeZoneName" : "Eastern Daylight Time"
}

Start coding with our client libraries

Client libraries make developing with the Google Maps web service APIs easier by providing simple, native implementations of common tasks, such as authentication, request throttling and automatic retry. The Time Zone API is available in the Java Client, Python Client, Go Client and Node.js Client for Google Maps Services.

Authentication, quotas, pricing, and policies

Activate the API and get an API key

To use the Time Zone API, you must first activate the API in the Google Cloud Platform Console and obtain the proper authentication credentials. You need to provide an API key in each request (or a client ID if you have a Premium Plan).

The Time Zone API Developer Guide is intended for website and mobile developers who want to include time data on maps provided by one of the Google Maps Platform APIs. It provides an introduction to using the API and reference material on the available parameters.
