Current month first and last day is wrong

I need to fetch the first and last day of the current month. I created the solution using the core JS new Date() method.

const date = new Date();
const firstDay = new Date(date.getFullYear(), date.getMonth(), 1);
const lastDay = new Date(date.getFullYear(), date.getMonth() + 1, 0);

console.log(firstDay.toUTCString(), lastDay.toUTCString()); //Tue, 31 Mar 2020 18:30:00 GMT Wed, 29 Apr 2020 18:30:00 GMT

When I try a similar thing in the browser's console, it prints the result as expected, i.e. 1st April 2020 and 30th April 2020, but testing it in the postman environment, gives the wrong result.

Can anyone please help to resolve this confusion?

Your code:

var d = new Date(),
  e = new Date(d.getFullYear(), d.getMonth(), 1),
  f = new Date(d.getFullYear(), d.getMonth() + 1, 0);
  
console.log(e.toUTCString() + "\n" + f.toUTCString());

so you get wrong result because you want to get the UTC string from local date, you need to make it UTC date in order to print UTC string correctly.

var d = new Date(),
  e = new Date(Date.UTC(d.getFullYear(), d.getMonth(), 1)),
  f = new Date(Date.UTC(d.getFullYear(), d.getMonth() + 1, 0));
  
console.log(e.toUTCString() + "\n" + f.toUTCString());
