Format duration, leave out / escape months and add it to days amount

[warri93]

Describe the bug Formatting a duration does not have the ability to escape months. Instead it just ignores them

For example we want to display PT11856H8M34S as years, days, hours, minutes & seconds. Leaving out the months.

dayjs.duration('PT11856H8M34S').add(0,'s').format('Y[y] D[d] H[h] m[m]') Output: 1y 9d 0h 8m

dayjs.duration('PT11856H8M34S').add(0,'s').format('Y[y] M[m] D[d] H[h] m[m]') Output: 1y 4m 9d 0h 8m

You can clearly see that we lose 4 months of days... How can we prevent this? It should output something like 1y 129d 0h 8m

Expected behavior Adding months to days value

• Day.js Version 1.11.2

The formatting of durations is similar to the formatting of dates: if you have a date like 2022-06-23T13:14:15 and format it with a format string YYYY-DD HH:mm:ss the month is not part of the output.
The same goes with duration: if you omit the M part, then the output will not include the months (and will not convert it to days, or hours or any other unit included in the output). Perhaps the documentation can be misinterpreted.

Using the asDays() function will get the duration as days - but only the whole duration (see documentation).

DD max 31 day, for duration, i need like 80day 23h 30m

That's what I understand, but dayjs cannot do that using format. You could create a small function that gets the values you need, e.g. like this:

const durationDayjs = dayjs.duration('PT11856H8M34S').add(0, 's')

const years = Math.floor(durationDayjs.asYears())  // 1
const days = Math.floor(durationDayjs.asDays()) - (years * 365)  // 129
const hoursWithFraction = (durationDayjs.asDays() % 1) * 24
const hours = Math.floor(hoursWithFraction) * 24  // 0
const minutes = Math.floor((hoursWithFraction % 1) * 60)
const seconds = durationDayjs.asSeconds() % 60  // 34
