How to Convert a Unix Timestamp to Time in JavaScript

Topic: JavaScript / jQueryPrev|Next

Answer: Use the new Date() Syntax

Simply multiply Unix timestamp by 1000 to convert it to a JavaScript time, because Unix timestamp measures time as a number of seconds, whereas in JavaScript time is fundamentally specified as the number of milliseconds (elapsed since January 1, 1970 at 00:00:00 UTC).

The following example demonstrates how to convert Unix timestamp to JavaScript time and extract date and time part from it. Let's try it out and see how it works:

// Timestamp in seconds
var unixTimestamp = 1651822834;

/* Create a new JavaScript Date object based on Unix timestamp.
Multiplied it by 1000 to convert it into milliseconds */
var date = new Date(unixTimestamp * 1000);

// Generate date string
console.log(date.toLocaleDateString("en-US"));   // Prints: 5/6/2022
console.log(date.toLocaleDateString("en-GB"));   // Prints: 06/05/2022
console.log(date.toLocaleDateString("default")); // Prints: 5/6/2022

// Generate time string
console.log(date.toLocaleTimeString("en-US"));   // Prints: 1:10:34 PM
console.log(date.toLocaleTimeString("it-IT"));   // Prints: 13:10:34
console.log(date.toLocaleTimeString("default")); // Prints: 1:10:34 PM
