How to Convert Unix Timestamps to a Readable Date Format in Angular

When working with timestamps in Angular, particularly Unix timestamps, many new developers often find themselves in a dilemma. You may have timestamps like deliveryDateFrom and deliveryDateTo, and your goal is to convert these into a readable date string for user interfaces. This guide will guide you through the solution step by step, demonstrating how to convert Unix timestamps into a well-formatted string like "Tuesday, June 13th Between 11am and 2pm".

Understanding Unix Timestamps

Unix timestamps are a standard way of tracking time, representing the number of milliseconds that have elapsed since January 1, 1970 (UTC). The timestamps you provided are:

Issues with Initial Attempts

You might have tried creating a Date object directly from the timestamps but found it confusing. Here’s a recap of a common approach:

This can work but is often too low-level for rendering a friendly string format like "Tuesday, June 13th". Let’s break it down properly.

Step-By-Step Solution

1. Creating a Date Object

Let’s start with the first timestamp to get a Date object:

2. Extracting the Day and Month

To format the day, month, and weekday, we can use the toLocaleString method. Here is how you can do this:

For the given timestamp, this will output a string like "Monday, September 27".

3. Formatting the Day with ‘st’, ‘nd’, ‘rd’, or ‘th’

To make your date user-friendly, you need to append the correct ordinal indicator (th, st, nd, or rd). For the example provided, you will add 'th' to 27:

4. Getting 12-Hour Format of Time

Next, you’ll want the 12-hour format for the time. Here’s how you can do that for both dates:

This will output times like 8PM, making it more readable.

5. Putting It All Together

Now that you have formatted the dates and times, you can easily put them together in your HTML template. You can use Angular’s interpolation to display the result as follows:

This will render a string like "Monday, September 27th Between 8pm and 8pm" in the UI.

Conclusion

By following these steps, you can successfully convert Unix timestamps in Angular into a user-friendly format that clearly communicates the date and time. Remember, the final output will vary depending on the actual timestamps you are using, but the structure remains the same. Happy coding!
