JavaScript - convert unix timestamp to human readable

In this article, we would like to show you how to convert unix timestamp to human readable in JavaScript.

Quick solution:

// ONLINE-RUNNER:browser;

const timestamp = 1630564245;     // unix timestamp in seconds
const date = new Date(timestamp * 1000);

console.log(date);  // Thu Sep 02 2021 08:30:45 GMT+0200 (Central European Summer Time)
console.log(date.toISOString());  // 2021-09-02T06:30:45.000Z

1. Convert unix timestamp to Date object

In this example, we display unix timestamp in human readable form by converting it to the Date object.

// ONLINE-RUNNER:browser;

const timestamp = 1630564245;     // unix timestamp in seconds
const date = new Date(timestamp * 1000);

console.log(date);  // Thu Sep 02 2021 08:30:45 GMT+0200 (Central European Summer Time)
console.log(date.toISOString());  // 2021-09-02T06:30:45.000Z

Output:

Thu Sep 02 2021 08:30:45 GMT+0200 (Central European Summer Time)
2021-09-02T06:30:45.000Z

Note:

We have already explained this solution in detail in the following article:

• JavaScript - convert unix timestamp to Date

2. Convert unix timestamp to time

In this example, we display unix timestamp in human readable form by converting it to the time string.

// ONLINE-RUNNER:browser;

const getTime = (timestamp) => {
  const date = new Date(1000 * timestamp); // unix timestamp in seconds to milliseconds conversion
  const time = date.toTimeString();
  const parts = time.split(' ');
  return parts[0];
};

// Usage example:
const timestamp = 1630564245; // unix timestamp in seconds
console.log(getTime(timestamp)); // 08:30:45

Output:

08:30:45
