Angular DatePipe is struggling to identify the date format

I am facing an issue in my Angular application where I need to display the date in the 'MM/dd/yyyy' format. The Web API is sending the date in the format of "2020-12-01T00:00:00".

Even though I am using the DatePipe, it does not recognize the date, unless I manually modify it to "2020-12-01T00:00:00.000Z". Then, the DatePipe is able to convert it to the desired 'MM/dd/yyyy' format.

let res = this.datePipe.transform(new Date('2020-12-01T00:00:00'),'MM/dd/yyyy');

let res = this.datePipe.transform(new Date('2020-12-01T00:00:00.000Z'),'MM/dd/yyyy');

The first code snippet does not work while the second one works perfectly. However, my API sends data in the first format. Can someone assist me in converting the date from the first format to the second format using Typescript?

Attempt:

const result = this.datePipe.Transform(new Date('2020-12-01T00:00:00').toISOString(),'MM/dd/yyyy');

  1. Perhaps the code snippet you provided was a simplified version to illustrate your problem. If you're utilizing DatePipe in your project, consider using the formatDate function instead. Essentially, DatePipe performs a null check and wraps the function in a try/catch block.
  2. When passing a Date object to either the pipe or the function, ensure that the object instance is being utilized. If issues arise, it could be due to the browser encountering difficulties parsing the date during new Date('...'). Test with 
    console.log(isNaN(new Date('2020-12-01T00:00:00')))
    . If the result is true, then the browser may be at fault.
  3. Both the pipe and the function are capable of handling strings, utilizing a regex for parsing them. Instead of encapsulating the value in a Date object, try passing the string directly to observe the outcome.
let res = this.datePipe.transform('2020-12-01T00:00:00','MM/dd/yyyy');
let res2 = this.datePipe.transform('2020-12-01T00:00:00.000Z','MM/dd/yyyy');
  1. In my testing with Angular 10 and Chrome on Windows, I did not encounter the same issue as you described.
