Option to make Sunday the first day of the week on calendar picker

In the U.S., and other countries I’m sure, Sunday is always noted as the first day of the week on calendars. One of the complaints I hear from my customers is that it’s hard to remap their mental model when picking dates. It would be great to have the option on the date field, or even a site config option, to set Sunday to be the first day of the week on datepickers.

I second this. Not having the option to choose the first day of the week for datepicker calendars significantly harms the user experience. The inconsistency with a user’s other calendars – i.e. Google Calendar or the user’s desk calendar – leads to errors during data entry.

Thank you!!!
