Is the Javascript date object always one day off?

Question

In my Java Script app I have the date stored in a format like so:

2011-09-24

Now when I try using the above value to create a new Date obje

if you're just looking to make sure the individual parts of the date stay the same for display purposes, *this appears to work, even when I change my timezone:

var doo = new Date("2011-09-24 00:00:00")

just add the zeros in there.

In my code I do this:

let dateForDisplayToUser = 
  new Date( `${YYYYMMDDdateStringSeparatedByHyphensFromAPI} 00:00:00` )
  .toLocaleDateString( 
    'en-GB', 
    { day: 'numeric', month: 'short', year: 'numeric' }
  )

And I switch around my timezone on my computer and the date stays the same as the yyyy-mm-dd date string I get from the API.

But am I missing something/is this a bad idea ?

*at least in chrome. This Doesn't work in Safari ! as of this writing
