Invalid Date with datejs

October 7, 2022

I need to convert string to date.

But I don’t understand why the end date is not converted from a string. Then I decided to use the daysJs library, but it gave the same thing

let date={
end:"15-10-2022",
start:"05-10-2022",
}
let range = {
        start:new Date(date.start),
        end: new Date(date.end),
};
      
console.log(range)

>Solution :

Running the code snippet embedded in Stack, I can see that your end property is null, presumably because the formattign for the dates is MM-DD-YYYY and you’re formatting them as DD-MM-YYYY. The simplest solution is to Swap your month and day in the date. Otherwise, just use MomentJS for its simplification of working with dates.

Formatting DD-MM-YYYY without moment:

let date = {
    end: '15-10-2022',
    start: '05-10-2022'
};
let range = {
    start: new Date(date.start.split('-').reverse().join('-')),
    end: new Date(date.end.split('-').reverse().join('-'))
};
console.log(range);

Formatting DD-MM-YYYY with moment:

let date = {
    end: '15-10-2022',
    start: '05-10-2022'
};
let range = {
    start: moment(date.start, 'DD-MM-YYYY'),
    end: moment(date.end, 'DD-MM-YYYY')
};
console.log(range);
