Let's enable Temporal by default #57127
Description
What is the problem this feature will solve?
The Temporal API is nearing completion in TC39 and is largely stable. It is not turned on by default in V8 just yet until it reaches stage 4 but platforms are starting to enable it by default. We ought to be able to go ahead and enable it by default in main
What is the feature you are proposing to solve the problem?
Enable Temporal by default but still marked as experimental
What alternatives have you considered?

how to enable it in the meantime?
targos commentedon Nov 4, 2025
There's no built-in way to do it. I would suggest to use a polyfill in the meantime.

Temporal is unflagged in V8 today - https://issues.chromium.org/issues/401065166#comment106
Heading for Chrome 144.

@targos that's what i figured in the end. i went for https://github.com/js-temporal/temporal-polyfill/ which looks like "the official" implementation. thank you for the answer (and sorry for answering back late)

Temporalwill now ship inchrome144betaas seen here blog. So is this a good time to revisit this issue ?Manishearth commentedon Dec 11, 2025
I think people are actively working on this, the issue is not abandoned for it to need to be "revisited".

fwiw we're at a point now where MDN is suggesting that Date is "considered legacy", that it's "baseline widely available", and that users should use Temporal if possible. Just wanted to note as I rewrote a small feature off of that suggestion only to find out it's not actually available in any non-browser runtime yet 🫠

@bnb the “baseline widely available” note in your screenshot refers to Date, not to Temporal. Temporal is not baseline widely available.
bnb commentedon Feb 11, 2026
ah fair, mistake on my end.
y-nk commentedon Feb 12, 2026
the Date object is far from being a legacy feature imho as most db connectors still use Date as base type for anything time related. That being said if we don't open Temporal by default, adoption will never start and we'll stay in that state forever 🤷
bnb commentedon Feb 12, 2026
I think calling it legacy in the browser in the evergreen environment we now live in makes sense, but calling it legacy in Node.js and other non-browser runtimes does... not, yes. It's also a language feature and not something for us to really make a call on unless the language wants to start warning on usage.
ljharb commentedon Feb 12, 2026
Date is conceptually legacy in an environment the literal instant Temporal appears. That doesn't mean it can ever be removed nor isn't in wide usage. That includes node as well as browsers.

Chrome 144 was released with the Temporal API
Edit: whoops, it was released a month ago

@bnb: For what it's worth, shortly after that comment was posted, Deno v2.7.0 stabilized it's temporal support (in Deno #31298). As of that reply, Deno did have it behind a

Are there any plans to backport Temporal to Node 24? Thank you.
richardlau commentedon May 20, 2026
There are not because support is heavily reliant on the version of V8 and the one in Node.js 24 is too old.
ljharb commentedon May 20, 2026
@richardlau could it be added to 24 by adding temporal_rs?
richardlau commentedon May 20, 2026
@ljharb I suspect not. At least not without an unknown number of V8 backports (if that is even practical). The version of V8 in Node.js 24 is pre-temporal_rs.
