For example I've 250 Days and I want to convert it into months and days using moment.js so do you have any idea how can I do that?

Example:

What I've: 250 Days

What I want: 8 Months and 7 Days

• javascript
• node.js
• momentjs

• Do you need to count months forward or backward starting from the current date-time? – Ihor Sakailiuk Commented Aug 7, 2019 at 5:59
• 1 why is 250 days 8 months and seven days? 250 days from 1 jan 2019 is 8 months 7 days (going forward), but it's 8 months 8 days from 1 feb 2019, 8 months 5 days from 1 mar 2019, 8 months 6 days from 1 apr 2019 ... see the problem with "what you want"? – Jaromanda X Commented Aug 7, 2019 at 5:59
• This days being calculated from today and forward! – Kunal Dholiya Commented Aug 7, 2019 at 6:03

You can use duration together with diff to get the duration between these 2 dates

const start = moment();
const end = moment().add(250, 'days');

const duration = moment.duration(end.diff(start));

const years = duration.years();
const months = duration.months();
const days = duration.days();

console.log(`years: ${years} months: ${months} days: ${days}`);

You can use diff and duration from moment to achieve this.

const currentDate = moment(new Date(), 'YYYY-MM-DD');
const futureDate = moment(currentDate).add(250, 'days');
const diff = moment.duration(futureDate.diff(currentDate));

console.log(`${diff.months()} Months and ${diff.days()} Days`);
// 8 Months and 6 Days

const futureDate = moment().add(250, 'days');
const duration = moment.duration(futureDate.diff(moment()));

console.log(`${duration.months()} Months and ${duration.days()} Days`);

Note: it's a simplified example without edge-cases
