Luxon js get day from week day number

Question

Moment had the option to get the day name based on week number (0 to 6). I see that luxon has day of the week, as number from 1-7 (Monday is 1, Sunday is 7)https://moment.github.io/luxon/#/parsing but I dont know how can I convert the week number to day name?

In moment

moment().day(0).format('ddddd'); // Sunday

In moment

moment().day(0).format('ddddd'); // Sunday

I'd have a look at luxon's Info.weekdays, this will give day names in various formats.

However the day numbering is slightly different to Moment, so you'll have to translate.

const { Info } = luxon;
// moment.js days of week: Sunday: 0 -> Monday: 6
const momentDays = [0,1,2,3,4,5,6];

console.log('Index', 'Long', 'Short');
momentDays.forEach(day => {
    // Luxon day indexes are Monday: 0 -> Sunday 6
    const luxonDay = (day + 6) % 7;
    console.log(day, Info.weekdays('long')[luxonDay], Info.weekdays('short')[luxonDay]);
})

.as-console-wrapper { max-height: 100% !important; top: 0; }
