Seems that the date format is only used in places with fully numeric dates, like 12/31/24.

Dates which are formatted in longer style formats are not affected by date format option.

Changing the language does not change this format either (tested English GB and Polish)

To expand on the reported issue (let me know if I ought to raise a separate issue), HASS has location and language settings but does not seem to have any locale setting (e.g: en-AU, es-ES, or es-CL) and selecting "English GB" the dev tools | statistics | fix issue dialog shows gives US date format:

Here is is using the US date format (mm/dd/yyyy). In the end I found that I must set my user date format explicitly.

Improvements:

• A locale configuration (best options)
• Make system default the much more common dd/mm/yyyy format instead of the US format
• Add system level default date format
• Fix the default format for en-GB to be dd/mm/yyyy

Hi, we are a group of computer science students that are planning to fix this issue as part of a course. Perhaps this issue can be assigned to me?

We don't typically assign issues to new contributors. Just feel free to put up a pull request when it's ready.

I don't think that is true, using English GB + the setting use language settings for date format you would get d-m-y.

[bramkragten]

@RobSmyth it is just using d-m-y when selecting en-gb here, can you check if your issue still exists?

Hi @bramkragten ,

Yes, using en-gb now does give GB date format.

Thank you

I still would like the option to see YYYY-MM-DD instead of YYYY/M/D... At least an additional option for it.

Local date format is still not respected.

This is still relevant when adding an event to a calendar. The event dialog box displays the date as mm/dd/yyyy irrespective of Country being set to Ireland under the General settings.
