API Access

TimeZoneDB provides simple RESTful interface API and returns structured XML or JSON responses. You need to register a free API key to start using our services.

Our API is free for personal and non-commercial usage. There are no limits on how many queries you can make, but there is a rate limit where you can only send request to the server once per second. Additional queries will get blocked.

If you are heavy user, or using this API for commercial purposes, please upgrade to premium service for more reliable and unlimited access.
