The Ultimate Guide to Date Formatting in JavaScript: Tips and Tricks for Formatting Dates
Before we get started with the specifics of date formatting, let’s provide an overview of what it entails. Date formatting involves converting a date object into a specific string format. The output format can vary depending on the data being used and its intended use. For example, a date for a blog post may be formatted differently than a date for a calendar event.
JavaScript provides the Date object to work with dates and times. The Date object allows you to work with dates and times in a standardized way. It is important to understand the Date object as it will be the primary tool we use for formatting dates in JavaScript.
Now, let’s dive into some tips and tricks for formatting dates in JavaScript.

- toLocaleTimeString()
- toLocaleString()
Now, let’s take a closer look at each technique:
toDateString()
The toDateString() method returns a string representation of the date object in a simplified formate. This method returns the date in the format of Www Mmm dd yyyy, where:
- Www represents the day of the week, formatted as “Sun” through “Sat”.

How to Format Dates in JavaScript: A Step-by-Step Guide
Now that you are familiar with the most common date formatting techniques, let’s get into a step-by-step guide for formatting dates in JavaScript. We will use the Date object and its methods to format the dates.
Step 1: Create a new date object
To create a new date object, use the new Date() syntax. This creates a new instance of the Date object with the current date and time. You can also pass a specific date to the constructor as a string or as individual arguments for the year, month, and day.
Example:
let date = new Date();
Step 2: Identify the format you want to use
Before you can format the date, you need to know what format you want to use. You can choose to use one of the previously discussed methods, or you can use a custom format. We will discuss custom formats in more depth later on.
Step 3: Use the appropriate method to format the date
After you have identified the format you want to use, you can use the appropriate method to format the date. To use a specific method, you simply call it on the Date object.
Example:
let date = new Date();
let dateString = date.toString();
This will create a new Date object with the current date and time, and then convert it to a string using the toString() method.
Step 4: Customize the date format
If you want to use a custom format, there are many options available. One popular option is to use moment.js, a third-party library for formatting dates and times. Moment.js provides many tools for formatting dates, including formatting strings, formatting dates and times together, and formatting relative dates.
Step 5: Troubleshoot common problems
When formatting dates in JavaScript, there are several common problems that can occur. Some of the most common problems include:
- Time zone issues – ensure that you use the correct time zone for your date formatting.
- Format issues – double check that you are using the correct format strings.
- Unexpected results – ensure that you have correctly called the method and are using the correct syntax.

Advantages and Disadvantages
Each formatting technique has its own advantages and disadvantages. Here are some of the most important:
- ISO 8601 format – advantages: universal format, easy to read by other programmers. Disadvantages: not ideal for human readability.
- Long format – advantages: easy to understand, good for human readability. Disadvantages: takes up more space and may not be necessary in all cases.
- Short format – advantages: compact, easy to read. Disadvantages: not ideal for precise times and may not be suitable for all situations.

By mastering date formatting techniques, you can ensure that your websites and applications are professional-looking and user-friendly. Whether you choose to use one of the pre-built methods or create a custom format, the key is to select the format that best suits your needs.
Date Formatting Shortcuts in JavaScript
JavaScript provides several shortcuts for formatting dates to save time and effort. These shortcuts use the options of the toLocaleString() method to format a date in a specific way. Here are some of the most common shortcuts:
- date.toLocaleDateString() – this shortcut returns a string representation of the date in the format of the local date string.
- date.toLocaleTimeString() – this shortcut returns a string representation of the time in the format of the local time string.
- date.toLocaleString() – this shortcut returns a string representation of the date and time in the format of the local date and time string.
To use these shortcuts, simply call the method on the Date object. You can also specify options to customize the formatting. For example:
let date = new Date();
let dateString = date.toLocaleDateString("en-US", { weekday: 'long', year: 'numeric', month: 'long', day: 'numeric' });
This will create a new Date object with the current date and time, and then format it into a long date format.
