Temporal_rs has been released!!! This is the first public release of Temporal_rs, a Rust implementation of the Temporal API powering Boa, Kiesel, V8 plus other engines. This will be shipping in Chromium soon More info in our blog post: boajs.dev/blog/2025/09...

Boa's temporal_js may turn out to be one of the most widely used implementations of the TC39 Stage 3 Temporal API 👍 An independent open source project having impact on the whole JS ecosystem. The Boa community has come along way since it was started by @jason-williams.co.uk seven years ago.

temporal_rs is a Rust library implementing the upcoming ECMAScript proposal Temporal. Not only is it being used in Boa but also V8 and other engines. You can find out more about the implementation process below.
