[SOLVED] Luxon js get day from week day number

Luxon js get day from week day number

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

Solution

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]);
})
