It is currently fully supported in Chrome, Edge, and Firefox, and is expected to reach full availability across browsers before the summer of 2026.

Opera support will probably appear 1-3 browser cycles after Chromium, which often means a few months later.
The Safari implementation is in development and can be tested in Safari Technology Preview by enabling the --use-temporal runtime flag.
Polyfill
Until Opera and Safari support Temporal natively, you can use the official polyfill:
