change the first day of the week with work week view - momentjs

Question

I'm trying to change the first day of the work_week view with react big calendar but I didn't found a way to do it... I was able to change the first day of the week view but nothing helped with work week... any ideas?
This is how I changed the first day of the week view:
import "moment/locale/en-gb";
moment.locale("en-gb", {
week: {
dow: 0,
},
});
const localizer = momentLocalizer(moment);

Unfortunately, the only way to do this is by defining a custom 'View', rather than using the 'work_week' view. First you can create the 'View', using the 'work_week' view as a template.
import PropTypes from "prop-types";
import React from "react";
import Week from "react-big-calendar/lib/Week";
import TimeGrid from "react-big-calendar/lib/TimeGrid";
function workWeekRange(date, options) {
return Week.range(date, options).filter(
(d) => [0, 1, 6].indexOf(d.getDay()) === -1
);
}
class MyWorkWeek extends React.Component {
render() {
let { date, ...props } = this.props;
let range = workWeekRange(date, this.props);
return <TimeGrid {...props} range={range} eventOffset={15} />;
}
}
MyWorkWeek.propTypes = {
date: PropTypes.instanceOf(Date).isRequired
};
MyWorkWeek.defaultProps = TimeGrid.defaultProps;
MyWorkWeek.range = workWeekRange;
MyWorkWeek.navigate = Week.navigate;
MyWorkWeek.title = (date, { localizer }) => {
let [start, ...rest] = workWeekRange(date, { localizer });
return localizer.format({ start, end: rest.pop() }, "dayRangeHeaderFormat");
};
export default MyWorkWeek;
The magic there is in the workWeekRange method, where I defined the days (zero index) to hide from the week. In this example I'm hiding Sunday, Monday and Saturday.
Also notice that I had to change my import statements for the Week and TimeGrid components.
The last thing I had to do was provide the custom 'View', as well as a title for the button in the Toolbar. You do this in your calendar props. The views prop changes from the standard array to an object.
return (
<Calendar
// other props
views={{
day: true,
month: true,
myweek: MyWorkWeek
}}
messages={{
myweek: 'Work Week'
}}
/>
You can see a working example in CodeSandbox.
