Setting the precision of a moment object (e.g., minutes, seconds)

05 Oct 2023

As developers, we often work with dates and times in our applications. JavaScript provides the moment.js library to make manipulating and formatting dates and times straightforward. One common task is to set the precision of a moment object, for example, setting the precision to minutes or seconds. In this blog post, we will explore how to achieve this using moment.js.

Prerequisites

To follow along with the examples in this blog post, you need to have moment.js library installed in your project. You can install it using npm:

npm install moment

Setting Precision to Minutes

To set the precision of a moment object to minutes, we can use the format() method of moment.js. Let’s look at an example:

const moment = require('moment');

const now = moment(); // Current moment object

const nowWithMinutesPrecision = now.format('YYYY-MM-DD HH:mm'); // Setting precision to minutes

console.log(nowWithMinutesPrecision); // Output: 2022-01-01 12:30

In the code above, we first import the moment library and create a moment object representing the current date and time. Then, we use the format() method with the desired format string 'YYYY-MM-DD HH:mm' to set the precision to minutes. Finally, we log the result, which will display the current date and time with minutes precision.

Setting Precision to Seconds

If you need to set the precision of a moment object to seconds, you can modify the format string in the format() method. Here’s an example:

const moment = require('moment');

const now = moment(); // Current moment object

const nowWithSecondsPrecision = now.format('YYYY-MM-DD HH:mm:ss'); // Setting precision to seconds

console.log(nowWithSecondsPrecision); // Output: 2022-01-01 12:30:45

Similar to the previous example, we modify the format string to 'YYYY-MM-DD HH:mm:ss' to include seconds precision. The resulting moment object will now have seconds precision.

Conclusion

In this blog post, we explored how to set the precision of a moment object using moment.js. We learned how to set precision to minutes and seconds. By manipulating the format string in the format() method, you can control the level of precision you need for your specific use case. Feel free to explore the moment.js documentation for more options and formatting patterns.
