How to Format a Date from YYMMDD to DD/MM/YYYY Using MomentJS

When working with dates in programming, you may encounter various formats that can create confusion and complexity. One common challenge arises when you receive dates in a condensed format such as YYMMDD, which often needs to be converted to a more readable format like DD/MM/YYYY. This is particularly important when you want to present data in a user-friendly way. If you’ve found yourself in this situation, you’re not alone! Today, we'll explore how to easily format a short date using MomentJS.

The Problem: Understanding the Date Format

In your project, you are receiving dates from an endpoint formatted as YYMMDD. Here’s a breakdown of the format:

YY: The last two digits of the year (e.g., 21 for 2021)

MM: The month (01 for January, 02 for February, etc.)

DD: The day of the month (01, 02,..., 31)

For example:

210626 represents the 26th of June, 2021.

Your goal is to convert this format into a more conventional DD/MM/YYYY format.

The Solution: Using MomentJS

Fortunately, using MomentJS makes this date transformation very straightforward! MomentJS is a popular JavaScript library for manipulating dates and times. Here's how you can handle the conversion with ease.

Step-by-Step Conversion

Install MomentJS: If you haven't already included MomentJS in your project, you can do so by adding it via a CDN or npm package.

Use the Moment Constructor: To convert your YYMMDD string to a date, you can use the Moment constructor with the proper format string.

Format the Date: Lastly, you can format the Date object to your desired output format.

Example Code

Here is the actual code you would use to perform the conversion:

Breakdown of the Code

Input: "210626" is the date in YYMMDD format.

Format: "YYMMDD" tells MomentJS how to read the given date.

Output: .format("DD/MM/YYYY") converts the date into the desired format.

Additional Considerations

Browser Compatibility: MomentJS works in most modern browsers, but always consider testing across environments to ensure consistent behavior.

Deprecation Notice: MomentJS is currently in maintenance mode, meaning that while it is reliable, you may want to explore more modern alternatives in the future, such as date-fns or Day.js.

Conclusion

Converting a date format from YYMMDD to DD/MM/YYYY can be done quickly and efficiently with MomentJS. By following the steps outlined above, you can make your date formatting interactions smooth and user-friendly. With just a few lines of code, you can ensure that your application presents dates in a format that users can easily understand.
