Describe the issue

When using manual input, the day and month get switched

Reproducible on https://getdatepicker.com/6/repl.html on multiple computers

Windows settings:
Language: English (United States)
Region: Netherlands
Regional Format: English (Europe)

1. Open the calendar
2. Pick a date (e.g. 7 December: 07/12/2022 13:13)
3. Change the month in the input field from 12 to 11 (07/11/2022 13:13) and click somewhere on the dialog without performing an action (e.g. on a name of a day)
4. Expected selected date: 7 November
5. Actual: selected date is 11 July. Also in the input field day and month are switched: 11/07/2022 13:13

Additional:
When changing the Regional Format to "English (United States)" it works correctly

JS date objects are constructed in en-US. Please see the customDateForm plugin

Thanks for the comment.
So the component only works correctly for users with en-US locale settings? If it only works with en-US out of the box, it should also format the output string to en-US, not to the locale of the user.
IMO input/output should be both the same, or manual input should be disabled

In javascript if you create a data e.g. new Date('07/12/2022') the date will be July 11, 2022. The old date picker used momentjs to attempt to handle formats that where not en-US format. In order reduce the external dependencies (and momentjs is no longer being updated), I opted to make use of the native JS date object and Intl. However, neither of those support providing custom format parsing. There are ways to provide custom parsing on your own or use the customDateFormat plugin.

That plugin might be rolling into the main picker but I haven't had time to do that.

Ok. I can confirm that using customDateFormat plugin the input/output is consistent.
