datepicker first day of week

I looked at docs and forum but can’t find how to set datepicker (or calendar) first column to Monday, not default Sunday. I suspect there is no such option, and that is really weird.

Thanks! Once again webix proved that it have a lot of options! Although I wish docs would allow me to find it more easily. I read ui.calendar API reference docs and searched forum by ‘monday’ ‘week start’ etc. Now I see that it’s actually can be found in calendar samples too, I wonder why I didn’t looked there from beginning.
