The default date format on our site is set to dd/mm/yyyy (d/m/Y).

We have a date field that has the following validation:
- Must be on or after today
- Required
- In dd/mm/yyyy format

This works very well in all browsers except IE and Edge where the submitted date value has the month and day flipped and causes PHP validation error. A screenshot has been attached.

The export of the test form is here:

  '#type': date
  '#title': Date
  '#default_value': today
  '#required': true
  '#min': today
  '#date_date_format': d/m/Y

This is a known issue with IE. @see

I recommend using the date list element.
