Sunset and sunrise times API
We offer a free API that provides sunset and sunrise times for a given latitude and longitude.
Please note that attribution is required if you use our API. Check "Usage limits and attribution" section below for more information.
API documentation
Ours is a very simple REST api, you only have to do a GET request to https://api.sunrise-sunset.org/json.
Parameters
- lat (float): Latitude in decimal degrees. Required.
- lng (float): Longitude in decimal degrees. Required.
- date (string): Date in YYYY-MM-DD format. Also accepts other date formats and even relative date formats. If not present, date defaults to current date. Optional.
- callback (string): Callback function name for JSONP response. Optional.
- formatted (integer): 0 or 1 (1 is default). Time values in response will be expressed following ISO 8601 and day_length will be expressed in seconds. Optional.

These are three sample requests for getting sunset and sunrise information from our API for a given location:

Status codes
The "status" field within the API response object contains the status of the request. The "status" field may contain the following values:
- "OK": indicates that no errors occurred;
- "INVALID_REQUEST": indicates that either lat or lng parameters are missing or invalid;
- "INVALID_DATE": indicates that date parameter is missing or invalid;
- "UNKNOWN_ERROR": indicates that the request could not be processed due to a server error. The request may succeed if you try again.
How to use the API from an AJAX request?
Use the parameter callback to receive a JSONP response and avoid cross domain boundaries:
https://api.sunrise-sunset.org/json?lat=36.7201600&lng=-4.4203400&callback=mycallback
Usage limits and attribution
The sunrise and sunset API can be used free of charge. You may not use this API in a manner that exceeds reasonable request volume, constitutes excessive or abusive usage. We require that you show attribution to us with a link to our site.
