By the end of this article, you will have a clear understanding of what JavaScript toDateString() is, how it works, and how to use it in your own projects. ππ
What is JavaScript toDateString()?
The toDateString() method is a method of the Date object in JavaScript. The Date object represents a specific point in time, measured in milliseconds since January 1, 1970 UTC (also known as the Unix epoch). π β³
The JavaScript toDateString() method returns the date portion of a Date object as a string, interpreted in the local timezone of the userβs browser. The date portion consists of the day of the week, the month, the day of the month, and the year. ππ
For example, if you create a Date object with the current date and time, and then call the toDateString() method on it, you will get something like this:
const today = new Date();
console.log(today.toDateString());
// Output: Tue Sep 19 2023
As you can see, the output is a string that contains the date information in a human-readable format. However, this format is not customizable or localized. It always uses the following format, separated by spaces: ποΈ
- First three letters of the weekday name π
- First three letters of the month name π
- Two-digit day of the month, padded on the left with a zero if necessary π
- Four-digit year (at least), padded on the left with zeros if necessary. May have a negative sign for dates before 0000 π
For example:
const date1 = new Date(2023, 0, 1); // January 1, 2023
console.log(date1.toDateString());
// Output: Sun Jan 01 2023
const date2 = new Date(1999, 11, 31); // December 31, 1999
console.log(date2.toDateString());
// Output: Fri Dec 31 1999
const date3 = new Date(-1000, 0, 1); // January 1, -1000
console.log(date3.toDateString());
// Output: Sat Jan 01 -1000
Why use JavaScript toDateString()?
You might be wondering why you would need to use JavaScript toDateString() when you can simply use the toString() method or other methods that return more information about a Date object. π€·ββοΈ
The main reason to use JavaScript toDateString() is that it returns only the date portion of a Date object, without any time or timezone information. This can be useful when you want to display or compare only the dates, without worrying about the differences in time zones or daylight saving time. ππ
For example, if you want to check if two dates are equal, you can use the toDateString() method to compare them as strings, instead of comparing them as numbers (which might give different results depending on the time zones). ππ°οΈ
const date1 = new Date(2023, 0, 1); // January 1, 2023
const date2 = new Date(2023, 0, 1, 12); // January 1, 2023 at 12:00 PM
console.log(date1 === date2); // false, because they are different objects
console.log(date1.getTime() === date2.getTime()); // false, because they have different milliseconds
console.log(date1.toDateString() === date2.toDateString()); // true, because they have the same date
Another reason to use JavaScript toDateString() is that it returns a simple and consistent format that is easy to read and understand. This can be helpful when you want to display the date in a user interface or a log file, without any unnecessary or confusing details. ππ
For example, if you want to show the date of a blog post or a comment, you can use the toDateString() method to display it in a clear and concise way. πποΈ
const postDate = new Date(2023, 0, 1); // January 1, 2023
const commentDate = new Date(2023, 0, 2); // January 2, 2023
console.log("Post date: " + postDate.toDateString()); // Post date: Sun Jan 01 2023
console.log("Comment date: " + commentDate.toDateString()); // Comment date: Mon Jan 02 2023
How to use JavaScript toDateString()?
To use JavaScript toDateString(), you need to have a Date object that you want to convert to a string. You can create a Date object in various ways, such as using the new operator, the Date.now() method, the Date.parse() method, or the Date.UTC() method. ππ οΈ
For example:
const today = new Date(); // creates a Date object with the current date and time
const epoch = new Date(0); // creates a Date object with the Unix epoch (January 1, 1970 UTC)
const birthday = new Date(1999, 11, 31); // creates a Date object with a specific date (December 31, 1999)
const timestamp = new Date(Date.now()); // creates a Date object with the current timestamp (milliseconds since the epoch)
const isoString = new Date(Date.parse("2023-01-01T00:00:00Z")); // creates a Date object from an ISO string (January 1, 2023 UTC)
const utcDate = new Date(Date.UTC(2023, 0, 1)); // creates a Date object from UTC values (January 1, 2023 UTC)
Once you have a Date object, you can call the toDateString() method on it without any parameters. The method will return a string that represents the date portion of the Date object in the local timezone. π°οΈπ
For example:
console.log(today.toDateString()); // Output: Tue Sep 19 2023
console.log(epoch.toDateString()); // Output:
Thu Jan 01 1970
console.log(birthday.toDateString()); // Output: Fri Dec 31 1999
console.log(timestamp.toDateString()); // Output: Tue Sep 19 2023
console.log(isoString.toDateString()); // Output: Sat Jan 01 2023
console.log(utcDate.toDateString()); // Output: Sat Jan 01 2023
Syntax and Parameters in JavaScript toDateString()
The syntax of the toDateString() method is as follows: π
dateObj.toDateString()
The toDateString() method does not take any parameters. It only works on a Date object, which is represented by the dateObj variable in the syntax. π€π
Return Value and Description
The toDateString() method returns a string that represents the date portion of a Date object, interpreted in the local timezone of the userβs browser. π π
The format of the returned string is: π
- First three letters of the week day name ποΈ
- First three letters of the month name π
- Two-digit day of the month, padded on the left with a zero if necessary π
- Four-digit year (at least), padded on the left with zeros if necessary. May have a negative sign for dates before 0000 π
For example:
const date = new Date(2023, 0, 1); // January 1, 2023
console.log(date.toDateString()); // Output: Sun Jan 01 2023
The returned string is not customizable or localized. It always uses the same format, regardless of the userβs language or region settings. If you want to format a date in a different way, you can use other methods, such as toLocaleDateString(), which we will discuss later. ππ
Examples and Usage of JavaScript toDateString()
In this section, we will show you some examples and use cases of how to use the JavaScript toDateString() method in JavaScript. ππ¨βπ»
Example 1: Get todayβs date as a readable string
One of the simplest and most common uses of the toDateString() method is to get todayβs date as a readable string. You can do this by creating a Date object with the current date and time, and then calling the toDateString() method on it. π
For example:
const today = new Date(); // creates a Date object with the current date and time
console.log(today.toDateString()); // returns today's date as a string
// Output: Tue Sep 19 2023
This can be useful when you want to display or store todayβs date in a user interface or a database, without any time or timezone information. π₯οΈποΈ
Example 2: Compare two dates using JavaScript toDateString()
Another use case of the toDateString() method is to compare two dates using their date portions only, without any time or timezone information. You can do this by creating two Date
objects with different dates (and possibly different times), and then calling the toDateString() method on both of them. Then, you can compare the returned strings using the equality operator (===
) or other comparison operators (<
, >
, <=
, >=
). πβ° For example:
const date1 = new Date(2023, 0, 1); // January 1, 2023
const date2 = new Date(2023, 0, 1, 12); // January 1, 2023 at 12:00 PM
console.log(date1 === date2); // false, because they are different objects
console.log(date1.getTime() === date2.getTime()); // false, because they have different milliseconds
console.log(date1.toDateString() === date2.toDateString()); // true, because they have the same date
console.log(date1 < date2); // false, because they have the same milliseconds
console.log(date1.toDateString() < date2.toDateString()); // false, because they have the same date
console.log(date1 > date2); // false, because they have the same milliseconds
console.log(date1.toDateString() > date2.toDateString()); // false, because they have the same date
console.log(date1 <= date2); // true, because they have the same milliseconds
console.log(date1.toDateString() <= date2.toDateString()); // true, because they have the same date
console.log(date1 >= date2); // true, because they have the same milliseconds
console.log(date1.toDateString() >= date2.toDateString()); // true, because they have the same date
This can be useful when you want to check if two dates are equal or in a certain order, based on their dates only. ποΈπ
Example 3: Format a date using JavaScript toLocaleDateString()
As we mentioned earlier, the toDateString() method returns a string that is not customizable or localized. It always uses the same format, regardless of the userβs language or region settings. If you want to format a date in a different way, you can use other methods, such as toLocaleDateString(). ππ
The toLocaleDateString() method is similar to the toDateString() method, but it returns a string that is formatted according to the userβs locale, which is determined by the userβs browser settings. The format of the returned string may vary depending on the locale, but it usually includes the following components: ππ
- Week day name π
- Month name π
- Day of the month π
- Year π
The JavaScript toLocaleDateString() method also accepts optional parameters that allow you to specify the locale and the formatting options. For example, you can use the locales parameter to specify a different locale than the userβs default one, and you can use the options parameter to specify which components of the date you want to include and how you want to format them. ππ
For example:
const date = new Date(2023, 0, 1); // January 1, 2023
// using the user's default locale
console.log(date.toLocaleDateString()); // Output: Sunday, January 1, 2023 (in en-US locale)
// using a different locale
console.log(date.toLocaleDateString("fr-FR")); // Output: dimanche 1 janvier 2023 (in fr-FR locale)
// using formatting options
console.log(date.toLocaleDateString("en-US", {weekday: "long", year: "numeric", month: "long", day: "numeric"})); // Output: Sunday, January 1, 2023 (in en-US locale)
console.log(date.toLocaleDateString("en-US", {weekday: "short", year: "2-digit", month: "short", day: "2-digit"})); // Output: Sun, 01/01/23 (in en-US locale)
This can be useful when you want to format a date in a way that is more suitable for the userβs preferences and expectations. ππ
Browser Compatibility and Specifications
The toDateString() method is a standard method of the Date object in JavaScript. It is supported by all modern browsers, such as Chrome, Firefox, Safari, Edge, and Opera. However, it may not be supported by some older browsers, such as Internet Explorer 8 or lower. ππ
The toDateString() method is defined in the ECMAScript Language Specification (ECMA-262), which is the official standard for JavaScript. The current version of the specification is ECMAScript 2020 (ECMA-262 11th Edition), which was published in June 2020. ππ
The toDateString() method is also part of the ECMAScript Internationalization API Specification (ECMA-402), which is an extension of the ECMAScript Language Specification that provides internationalization and localization features for JavaScript. The current version of the specification is ECMAScript Internationalization API Specification 2nd Edition, which was published in December 2016. ππ

Here are some frequently asked questions and answers about the toDateString() method:
Q: How do I get the time portion of a Date object as a string?
A: You can use the toTimeString() method, which returns the time portion of a Date object as a string, interpreted in the local timezone of the userβs browser. The time portion consists of the hours, minutes, seconds, and milliseconds. β°π
For example:
const date = new Date(2023, 0, 1); // January 1, 2023
console.log(date.toTimeString()); // Output: 00:00:00 GMT+0530 (India Standard Time)
Q: How do I get both the date and time portions of a Date object as a string?
A: You can use the toString() method, which returns both the date and time portions of a Date object as a string, interpreted in the local timezone of the userβs browser. The format of the returned string is: β°ποΈ
- Week day name π
- Month name π
- Day of the month π
- Year π
- Hours β°
- Minutes β°
