Oops, I'm just realizing that Firefox might not have any internationalization support for Haiti. Using the i18n scheme for French would be a huge improvement.

(new Intl.DateTimeFormat("ht", { dateStyle: "full" })).format(new Date("2020-03-01"))
-> "Saturday, February 29, 2020"

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'Core::JavaScript: Internationalization API' component, and is moving the bug to that component. Please revert this change in case you think the bot is wrong.

That's because ht is not the right BCP47 language identifier for Haiti. It's fr-HT:

(new Intl.DateTimeFormat("fr-HT")).format(new Date("2021-08-04"))
"03/08/2021"

You can verify that by checking (new Intl.DateTimeFormat("fr-HT")).resolvedOptions().locale

and the list of locales here: https://github.com/unicode-org/cldr-json/tree/master/cldr-json/cldr-dates-modern/main

Closing as INVALID per comment #3.

ht is the language identifier for Hatian Creole, the other official language of Haiti. https://unicode-org.github.io/cldr-staging/charts/latest/supplemental/language_territory_information.html

I suppose I should take it up with CLDR, since they seem not to have published to https://github.com/unicode-org/cldr-json/tree/master/cldr-json/cldr-dates-modern/main yet?

yes! And for many use cases you can also suggest they add fallback from ht to fr-HT to improve on the current ht -> en-GB fallback :)
