How to get only date and time from utc time in javascript

i want to convert utc time to ist time , im getting time like this. i want to remove "GMT+0530 (India Standard Time)"
Thu Jul 19 2018 18:06:14 GMT+0530 (India Standard Time)
Expected result
Jul 19 2018 18:06:14 or 19/7/2018 06:06 PM
sample data
2018-07-19T16:36:21.065Z
code
function UtcToIst(data) {
var dt = new Date(data);
return dt;
}

I achieved it in the following way. Please correct me, if I am wrong.
var data = '2018-07-19T16:36:21.065Z';
function UtcToIst(data) {
var dt = new Date(data);
return dt;
}
var updDate = UtcToIst(data).toLocaleDateString();
var updTime = UtcToIst(data).toLocaleTimeString();
var updDateTime = updDate + ", " + updTime;
console.log(updDateTime); // 7/19/2018, 9:36:21 AM

Javascript date conversion does not fail

I have an input date string like so "30/09/1992", and I found this code to suit my need. PFB the code.
var input1 = "30/09/1992";
var isVaidDate = false;
var actualDate = "";
try{
var pattern = /^(\d{1,2})\/(\d{1,2})\/(\d{4})$/;
var arrayDate = input1.match(pattern);
var actualDate = new Date(arrayDate[3], arrayDate[2] - 1, arrayDate[1]);
var isVaidDate = typeof dt.getMonth === 'function';
}catch(e){var output1 = false;}
print(isVaidDate);
print(actualDate);
The above code works fine but when I set the input as "31/09/1992" or "40/09/1992" I am expecting invalid date to come but I get the below output.
for "31/09/1992":
true
Thu Oct 01 1992 00:00:00 GMT+0530 (India Standard Time)
for "40/09/1992":
true
Thu Oct 10 1992 00:00:00 GMT+0530 (India Standard Time)
How should I get this to fail when i pass these two strings. Thanks. Also what is going on and why it didnt fail, would also be useful :)

This example can help you:
var dateString = 'Mon Jun 24 2013 05:30:00 GMT+0530 (India Standard Time)';
var myDate = new Date(dateString);
var final_date = myDate.getDate()+"-"+(myDate.getMonth()+1)+"-"+myDate.getFullYear();
Here you can verify each variable as day, month and year.

Customize date and time in javascript

I need date and time in this format in javascript.
2016/02/17-14:31:36
Currently I am using
var data = new Date();
But this gives Date {Fri Feb 26 2016 18:38:45 GMT+0530 (India Standard Time)}

var d = new Date(),
year = d.getFullYear(),
month = ('0'+(d.getMonth()+1)).slice(-2),
day = ('0'+d.getDay()).slice(-2),
hour = ('0'+d.getHours()).slice(-2),
minute = ('0'+d.getMinutes()).slice(-2),
second = ('0'+d.getSeconds()).slice(-2);
var dateString = year+'/'+month+'/'+day+'-'+hour+':'+minute+':'+second;
Next time, please google yourself. Thanks.
Edit
Now it also has those leading zero's.

Date issues in JavaScript

The code below mentioned is for comparision of date. Both date1 and mydate have similar values,But if i compare its not entering if loop. Any help appreciated
var date_arr = new Array( "Jan", "Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec");
var Avl_date = document.getElementById("Available_Date").value;
var V_date1 = Avl_date.split('-');
var date1 = new Date (V_date1[2], date_arr.indexOf(V_date1[1]),V_date1[0]);
var myDate = new Date();
myDate.setHours(0,0,0);
//Thu Dec 04 2014 00:00:00 GMT+0530 (IST) --> date1
//Thu Dec 04 2014 00:00:00 GMT+0530 (IST) --> mydate
if(myDate.getTime() === date1.getTime())
{
//Not entering the loop
}

You're not setting the milliseconds of myDate to 0, so it keeps its original milliseconds. Use:
myDate.setHours(0,0,0,0);

Barmar is correct. setting the milliseconds will solve your problem.

How to compare the date part alone from a date time value

I have two variables namely
date1 = Mon Nov 25 2013 00:00:00 GMT+0530 (IST)
date2 = Mon Nov 25 2013 14:13:55 GMT+0530 (IST)
When I compare the two dates I get that date2 is greater which I need is correct. But I do not want to check the time part of the two dates I have. How could I get the date part alone from these two dates and compare it?
var today = new Date(); //Mon Nov 25 2013 14:13:55 GMT+0530 (IST)
d = new Date(my_value); //Mon Nov 25 2013 00:00:00 GMT+0530 (IST)
if(d>=today){ //I need to check the date parts alone.
alert(d is greater than or equal to current date);
}

Try clearing the time using Date.setHours:
dateObj.setHours(hoursValue[, minutesValue[, secondsValue[, msValue]]])
Example Code:
var today = new Date();
today.setHours(0, 0, 0, 0);
d = new Date(my_value);
d.setHours(0, 0, 0, 0);
if(d >= today){
alert(d is greater than or equal to current date);
}

The best way would be to modify the accepted answer's if statement as follows
if(d.setHours(0,0,0,0) >= today.setHours(0,0,0,0))
In this way, you can easily check for equality as well because the return type for setHours() is integer.

Try:
var today = new Date(); //Mon Nov 25 2013 14:13:55 GMT+0530 (IST)
var d = new Date(my_value); //Mon Nov 25 2013 00:00:00 GMT+0530 (IST)
var todayDateOnly = new Date(today.getFullYear(),today.getMonth(),today.getDate()); //This will write a Date with time set to 00:00:00 so you kind of have date only
var dDateOnly = new Date(d.getFullYear(),d.getMonth(),d.getDate());
if(dDateOnly>=todayDateOnly){
alert(d is greater than or equal to current date);
}

var StartDate = $("#StartDate").val();
var EndDate = $("#EndDate").val();
if ((( EndDate - StartDate)/ (86400000*7))<0)
{
alert("Start Date Must Be Earlier Than End Date"); $("#StartDate").focus();
error = true;
return false;
}
