How do I format a date in JavaScript?

I would like to simplify the display of a date (2016-06-26 05:23:55) which on discord.js gives this:
Sun Jun 26 2016 05:23:55 GMT + 0200 (Central European Daylight Time)
I would like to have this : Saturday June 26, 2016 at 05:23

I'd suggest using a library such as date-fns to format the date.
have a look at their docs: https://date-fns.org/v2.16.1/docs/format
You don't have to, but you'll have to it manually (array of months, pick Xth month, ...)

I have HTML Date inputs that return a string in the format of 'YYYY-MM-DD'
I then want to put this into the Date Constructor so that I can get it converted into ISOFormat (for use of Mongo Querying)
However, the results are unexpected.
Doing new Date('2020-06-25') returns "Wed Jun 24 2020 20:00:00 GMT-0400 (Eastern Daylight Time)". Note that this is the day prior. Why does this happen and how can I change this to get the current date? THanks
When you create a new Date object in JavaScript, it expects the argument to be in GMT. It then converts it to your local timezone GMT-0400, which explains why its 4 hours off. You can set the timezone by appending it to the date string: new Date('2020-06-25 GMT-0400') should give you "Thu Jun 25 2020 00:00:00 GMT-0400".

Get timestamp with milliseconds in Javascript [duplicate]

I want to get the current date including the milliseconds. I know that Date.now() is returning the Unix epoch time in milliseconds, but the object Date contains only the Date and timestamp with second precision.
console.log("Time: " + new Date);
Time: Tue Apr 14 2020 12:21:26 GMT+0200 (Central European Summer Time)
But I want it to look like this:
Time: Tue Apr 14 2020 12:21:26.500 GMT+0200 (Central European Summer Time)
Is there a way to change the format in order to display the milliseconds as well or do I need to concatenate the Date string with new Date().getMilliseconds();?
You can use moment.js to achieve the format you need, and the other option is to concatenate manually
console.log(moment().format('YYYY-MM-DD HH:mm:ss.SSS'))

I've tried this code (new Date()).toUTCString() but the result is like
Sun, 22 Apr 2018 10:45:19 GMT
Easiest way is to leverage MomentJS - you can then use:
moment().format('MMM DD, YYYY hh:mm:ss A')

Without using moment.js, is there a way to construct a date in a specific timezone.
For example, I have two strings:
var date = '2018-01-23';
var time = '12:00';
I can construct the date like so:
var constructedDate = new Date(date.substring(0,4), date.substring(5,7)-1, date.substring(8,10), time.substring(0,2), time.substring(3,5));
which provides output of:
Tue Jan 23 12:00:00 GMT+00:00 2018
However, I am looking for output in a particular timezone (e.g +11:00)
Tue Jan 23 12:00:00 GMT+11:00 2018
Alternatively, is there a way to offset the date -11 hours so when I use the GMT date in my application it will be correct.

In JavaScript, when do/don't Dates get converted? [duplicate]

different result for yyyy-mm-dd and yyyy/mm/dd in javascript when passed to "new Date" [duplicate]
(2 answers)
Closed 6 years ago.
I'm confused because typing the same date in a different format results in two different date outputs, the first converted and the second, not. Here is the code:
var x = new Date("2015-03-25"); // outputs Tue Mar 24 2015 17:00:00 GMT-0700 (PDT)
var y = new Date("03/25/2015"); // outputs Wed Mar 25 2015 00:00:00 GMT-0700 (PDT)
The way dates are parsed by browsers is a huge pile of unpredictable inconsistency. You should not attempt it. Here's the full rundown in case you're curious: http://dygraphs.com/date-formats.html
If you want consistent parsing you should implement it yourself or us a library that does it. Momentjs is widely used: http://momentjs.com/
