Date Time Format with Am Pm in Javascript
One way to format a JavaScript date-time format to the 12-hour AM/PM format is to create your own function. The hour property is set to numeric to display hours in digital format. We have the formatAMPM function, which uses a JavaScript date object as a parameter. We can format a JavaScript date-time format in a 12-hour format using vanilla JavaScript or moment.js. And then we change the hours to the 12-hour format using the % operator to get the rest when divided by 12. Approach 1: In this approach, we modify the DateTime format using only native methods. Simply put, we apply the Modulo operator “%” to find the time in 12-hour format and use the conditional operator “?:” to apply “AM” or “PM”. Sometimes we may want to display a JavaScript date/time in AM/PM format of 1 hour. Approach 2: In this approach, we use a built-in toLocaleString() method to change the format of the specified date to am-PM format. Locale and options arguments customize the behavior of the function and allow applications to specify the language formatting conventions to use.
In older implementations that ignore locale and option arguments, the locale and shape of the returned string depend entirely on the implementation. To simplify the formatting of a date/time in AM/PM format, we can use the toLocaleString method. In the function we call getHours tio get the hours in 24-hour format. You can convert the current time to 12 hours using a line The default value of each date/time component property is not set, but if not all the Hour, Minute, and Second properties are set, the hour, minute, and second properties are assumed to be “numeric.” This example shows some of the variations in localized time formats. To get the format of the language used in your app`s UI, be sure to specify that language (and possibly some fallback languages) with the locale argument: we can retrieve the times and minutes from the current date and time. If the hourly value is greater than 12, it is PM, otherwise AM. Next, we convert the minutes into a string with toString and call padStart to fill a string with 0 if it is a number. JavaScript uses the default 24-hour format for DateTime. However, the time of day in JavaScript can be displayed with different approaches in the 12-hour AM/PM FORMAT. We will look at some of them in this article. toLocaleString(): Returns a string representation of the date object.
The 2 arguments Locale and Options allow you to customize the behavior of the method. The toLocaleTimeString() method returns a string with a language-sensitive representation of the temporal portion of the date. The new locale and options arguments allow applications to specify the language formatting conventions to use. These arguments can also customize the behavior of the function. We call toLocaleString on our date object with the locale and an object with some options. Simply using this method without specifying a locale returns a formatted string in the default locale and with the default options. We can replace toLocaleString with toLocaleTimeString and get the same result. More outdated implementations ignore the arguments of the locale and options. Under these circumstances, the shape of the returned string depends entirely on the implementation.
We can also use moment.js to format a date object in a 12-hour date-time format. When formatting a large number of dates, it is best to create an Intl.DateTimeFormat object and use the function provided by its format property. Use the Date methods to set and retrieve the time and create a time chain, something like the code snippet. . To run the above program, you must use the following command − The results provided by toLocaleTimeString() can be customized with the option argument: {{if IsAuthorComment == true}}{{html GrabUrls(CommentBody)}}{{else}}{{html CommentBody}}{{/if}} Web Developer.

This produces the following output on the console − new Date(Date.now() + 2 * 60 * 60 * 1000).toLocaleTimeString(`en-US`, { hour: `numeric`, hour12: true, minute: `numeric` }); For more information about these settings and how to use them, see the Intl.DateTimeFormat() constructor. The above code has been tested in the following browsers. [edit] Just for fun, a more generic approach with 2 Date.prototype extensions has been added.
Next, we create the ampm variable and render it `am` or `pm` depending on the value of the hours. .
