JavaScript allows you to work with dates are strings as well as objects. But we have to be careful while interchanging dates into string and vice versa since web browsers convert strings to date objects as per local time zone, by default. Sometimes you may need to convert UTC date time to local date time in JS. In this article, we will learn how to do this.
How to Convert UTC Date Time to Local Date Time in JS
There are two ways to represent date strings as UTC date time.
var date_string = '6/29/2011 4:52:48 PM UTC'; OR var date_string = '2011-06-29T16:52:48.000Z'
In both these cases, you just need to pass them into Date() constructor to obtain a date object as per local time zone.
var localDate = new Date(date_string);
Thereafter, if you want to display date as a string, use toLocaleString() function.
console.log(date.toLocaleString());
While working with UTC date time, make sure that UTC datetime string has either Z or UTC suffix. This will allow the strings to be parsed correctly. If they are not present in your date string, please add it, before you proceed further.
var date_string = "2011-06-29T16:52:48"; var localDateTime = new Date(datetime + 'Z');
In this short article, we have learnt how to convert UTC time to local date time.
