hour: "numeric" is shown as "2-digit" if paired with weekday but not month or year

This seems to be a bug?

const format = {
  weekday: 'long',
  hour: 'numeric',
  minute: '2-digit'
};

return dt.toLocaleString(format);

Expected output: 5:21 Actual output: 05:21

If month or year are added to the format object, or if weekday is removed, hour is correctly formatted as numeric.

I’m also on a Mac. Doesn’t seem like it could be because of German, since yours also says “Wednesday”. But maybe it has something to do with it.

In any case, with German specified in the Intl constructor, I also get Samstag, 05:21, and I also see the dropped 0 if I remove the weekday.

The Intl API spec is pretty complicated and has some allowances for the implementation to to make decisions based on combining the parameters you put in and the information it has about how the language works; it’s not as straightforward as it looks. However, I am not deeply familiar with the ins and outs, so I’m not sure whether it’s a bug in Chrome or not. Perhaps it is, in which case, a ticket with Chromium is needed.

But in any case, there’s nothing much Luxon can do about it. Luxon is just the messenger.
