How to make html5 "week" input type start on sunday

Question

<input type="week" /> 

shows the highlighted starting week as Monday. Is there a way to make it show Sunday as the start of the week to prevent confusion?

Answer 1

I don't believe this is possible at this time. You can find the spec for the "week" input type here:

http://www.w3.org/TR/html-markup/input.week.html

There is no mention of specifying the start day.
