I have a date coming back in this format 2021-12-03T00:00:00.000Z which I then convert to an ISO date string and then construct a new Date() based on the split ISO string. The issue is that my date properly gets formatted with every month except December. Anytime I pass a December date, the logic always converts it to be January of the next year.
Code
//bill.date_paid at this point = '2021-12-03T00:00:00.000Z'
let isoDateString = new Date(bill.date_paid).toISOString().split('T')[0].split('-');
//isoDateString = ['2021', '12', '03'];
bill.date_paid = new Date(isoDateString[0], isoDateString[1], isoDateString[2]).getTime();
//date conversion above = 1641193200000 which is equal to a January date...
But why?
To convert your iso date to the mm/dd/yyyy format you can use a Intl.DateTimeFormat object like below :
const date = new Date('2021-12-03T00:00:00.000Z');
const result = new Intl.DateTimeFormat('en-US').format(date);
console.log(result);Why you don't convert it directly to time?
let date_paid = '2021-12-03T00:00:00.000Z'
let date = new Date(date_paid).getTime()
console.log(date)You can try this
date = new Date('2021-12-03T00:00:00.000Z');
console.log((date.getMonth()+1)+'/'+(date.getDate()) + '/'+date.getFullYear());Also you can use moment.js
console.log(moment(new Date('2021-12-03T00:00:00.000Z')).format("MM/DD/YYYY"))<script src="https://cdnjs.cloudflare.com/ajax/libs/moment.js/2.29.1/moment.min.js"></script>
