How to get the day of the week in accusative in momentjs?

Question

JavaScript

momentjs has the names of the days of the week in the nominative and accusative cases. How can I get a name in the accusative case?
I usually get this:

moment.weekdays(2);
moment(str).format("dddd");

Source:

moment.updateLocale('en', {
    weekdays : {
        standalone: 'Воскресенье_Понедельник_Вторник_Среда_Четверг_Пятница_Суббота'.split('_'),
        format: 'Воскресенье_Понедельник_Вторник_Среду_Четверг_Пятницу_Субботу'.split('_'),
        isFormat: /\[ ?[Вв] ?(?:прошлую|следующую|эту)? ?\] ?dddd/
    }
});
