Convert Date string to Object with current timezone format [duplicate]

I have this code to add a reminder to a calendar
function addCalendarEvent(eventDate, eventTitle){
let dateObj = new Date(eventDate);
let calendarId = "me#gmail.com";
let cal = CalendarApp.getCalendarById(calendarId);
let event = cal.createAllDayEvent(eventTitle, dateObj)
event.addEmailReminder(420)
}
The eventDate is passed into the function as a string in the format dd/MM/YYYY but the output from let dateObj = new Date(eventDate); is in american format. ie. 02/10/2020 comes out as Mon Feb 10 2020 00:00:00 GMT+0000 (Greenwich Mean Time). Any help correcting this would be great. Dates give me an absolute headache

In the end I decided that just working with date objects from the off would be easiest

This will give you the date object of the string in the format dd/MM/YYYY
function ddmmyyyytFormatterWithTime(date) {
var dateDiv = date.split('/');
var date = new Date();
date.setDate(dateDiv[0]);
date.setMonth(--dateDiv[1]); // -- since it starts from 0
date.setFullYear(dateDiv[2]--);
return date;
};
function ddmmyyyytFormatter(date) {
var dateDiv = date.split('/');
var date = new Date();
date.setHours(0, 0, 0, 0); // to reset time
date.setDate(dateDiv[0]);
date.setMonth(--dateDiv[1]); // -- since it starts from 0
date.setFullYear(dateDiv[2]);
return date;
};
var date = ddmmyyyytFormatter("10/02/2020");
var dateWithTime = ddmmyyyytFormatterWithTime("10/02/2020");

new Date() always read dd/mm/yyyy as mm/dd/yyyy(month first) hence day and month values get mixed resulting in NaN/Error [duplicate]

When converting date for example:
var dateObj = new Date("10/01/2019");
console.log(dateObj);
returns Tue Oct 01 2019 00:00:00 i.e. it takes in the day as month and likewise with the month value
How to make new Date() to take dd/mm/yyyy ??

Answer is here: https://stackoverflow.com/a/33299764/6664779
(From original answer) We can use split function and then join up the parts to create a new date object:
var dateString = "23/10/2019"; // Oct 23
var dateParts = dateString.split("/");
// month is 0-based, that's why we need dataParts[1] - 1
var dateObject = new Date(+dateParts[2], dateParts[1] - 1, +dateParts[0]);
document.body.innerHTML = dateObject.toString();

I'm trying to convert a date in string format to a Date object in JavaScript. The date is coming from the openweathermap.org API, which gives the date string in the following format:
'2018-04-28 09:00:00' or 'yyyy-mm-dd hh:mm:ss'
I know that the JavaScript Date class can take other string formats of dates, but this one returns NaN when I try anything with it. How can I convert a date string, like the one above, and convert it easily to a JavaScript object? Thanks!

Since you are getting NaN while directly converting the string to date. You can split the string on spaces, - and : and then pass the value to date constructor and generate the date object.
const str = `2018-04-28 09:00:00`;
const [date, time] = str.split(' ');
const [year, month, day] = date.split('-');
const [hh, mm, sec] = time.split(':');
const dateObj = new Date(year, month - 1, day, hh, mm, sec);
console.log(dateObj);
As pointed out by #RobG, this could also be done using the regex.
const str = `2018-04-28 09:00:00`;
var b = str.split(/\D/);
var date = new Date(b[0],b[1]-1,b[2],b[3],b[4],b[5]);
console.log(date);
const str = `2018-04-28 09:00:00`,
date = new Date(...(str.split(/\D/).map((v,i)=>i==1?--v:v)));
console.log(date);

Just try new Date(str)
d = new Date("2018-04-20 09:00:00")
Fri Apr 20 2018 09:00:00 GMT+0800 (Hong Kong Standard Time)
d.getDate()
20

I want to add 30 days to current date and get in a format.
Im confused to add a 30 to a date and get new.
Its pure JS Solution needed.
Format : June 10, 2017

var date = new Date(); // Now
date.setDate(date.getDate() + 30); // Set now + 30 days as the new date
console.log(date);

Im assuming you are using datejs?
var newDate = Date.today().add(30).days();

try following:
var yourDate = new Date();
var numberOfDaysToAdd = 30;
console.log(yourDate.setDate(yourDate.getDate() + numberOfDaysToAdd));

I want to remove the time <<14:20:58 GMT+0100 (CET)>>

Try ...
var x = new Date()
var myVar = x.toDateString();
This will only provide the date ...
