Status: RESOLVED FIXED

(Core :: JavaScript: Internationalization API, enhancement, P3)

Description

[André Bargull [:anba]]

The spec PR https://github.com/tc39/ecma402/pull/346 adds support for the "dayPeriod" option to Intl.DateTimeFormat.

Example:

js> new Intl.DateTimeFormat("en", {dayPeriod: "short"}).format(new Date("2019-07-23T12:00:00"))      
"noon"
js> new Intl.DateTimeFormat("en", {dayPeriod: "short"}).format(new Date("2019-07-23T08:00:00"))  
"in the morning"

From https://github.com/tc39/ecma402/pull/346#issuecomment-515873310:

The implementation of this PR is now blocked by the following two ICU bugs:

• https://unicode-org.atlassian.net/browse/ICU-20740
• https://unicode-org.atlassian.net/browse/ICU-20741

And https://unicode-org.atlassian.net/browse/CLDR-13184 maybe also worth looking into.

ICU bugs were fixed last month. Is there any other issue blocking this bug?

Comment 6

[André Bargull [:anba]]

I don't think there are any blockers left. At this point we're just waiting for the ICU-67 release.
