HTML 5 - Input type date formatting on iOS

Question

I am using an HTML 5 form on an iPhone. This form has an input element like the following:

W

Answer 1

No.

There are two formats at play:

• displayed format
• internal format exposed to JavaScript and sent to the server

You cannot change the display format. It's up to the browser to decide how the date is presented to the user (in practice it's determined by system's locale).

You cannot change the internal format either. It's always ISO8601, regardless of browser/locale.
