CONVERT STRING TO DATE JAVASCRIPT ISO

You must specify the expected format of the text representing a date and time.There are three subtasks to correctly converting text into a DateTime: The methods that convert strings to DateTime objects enable you to provide detailed information about the formats you expect and the elements of a date and time your application needs. Still others need to specify both the date and time. Some time representations use a 24-hour clock, others specify 'AM' and 'PM.' Some applications need only the date. Different cultures use different orders for day, month, and year. Surprisingly, the new Date() also supports the date parameters be passed as arguments, and we get the date object as output.Parsing strings to convert them to DateTime objects requires you to specify information about how the dates and times are represented as text. Sometimes, if the date does not conform to the expected format, we will have to manually work it out by splitting the date string, extracting the values, and convert them to a date object.

Split String and Convert It to Date in JavaScriptīoth the Date.parse() and the new Date() functions are designed based on the ISO 8601 extended date format.

Date.parse() internally uses the new Date() for parsing of date, hence the formats accepted by the new Date() function will also be supported in the Date.parse() function.

Compared to the Unix Time Stamp, the Date.parse() returns milliseconds that can be used for precision comparison of dates even without converting them to actual date objects with new Date().

Date.parse() is similar to the new Date() except for the return type, which makes it suitable for checking if a date value is of a correct format and can also be used to assign a date by using the tTime(Date.parse(DateString)).

The !isNaN(Date.parse(d)) silently rejects the improper date value and logs the value that are successful in conversion. Hence if the stringsFromAPI was a value coming from the backend, then the above function will convert only those dates that conform to the acceptable format. Hence, it will not be understood by the Date.parse() function nor by the new Date() function. Note that here the date 20-11-2021 is of the format DD-MM-YYYY. It is similar to the timestamp format with the difference that instead of seconds, Date.parse() returns a milliseconds value.

It converts the parsed date to a number representing the milliseconds that have passed since midnight time. Hence it will require further processing if you expect a date object. It returns a numeric value instead of a date object. Use the Date.parse() Function to Convert String to Date in JavaScriptĭate.parse() is an alternate option to convert the string date. In case we are using a value passed from the backend via API for conversion, we should make sure that the format passed is as understood by the new Date() function, and it is good to have a check that new Date() returns a valid date object.

new Date() can also convert a string of the format 12:30 or even MM DD YYYY HH:mm.

For a different format that cannot be comprehended by new Date(), it is better to split the string and pass them as arguments into the new Date(), as introduce later in this article.

new Date() can be used to convert the string into a date only if it qualifies the ISO 8601 format YYYY-MM-DD hh:mm:ss.

If we have a different string format that does not conform to ISO 8601 standards, the new Date() will not be able to parse the date and will return as an Invalid date. The new Date() function can process strings in the format YYYY-MM-DD or YYYY/MM/DD. Sat 00:00:00 GMT+0530 (India Standard Time)Īs you see from the above examples, the only accepted string format for the date is 2021-05-/2/29.

For example, refer to the code as follows: Other date formats may not be converted to a date object by this method. The string format needs to be YYYY-MM-DD, the ISO 8601 format, for it to work. When we pass a date in string format to the new Date(), it is converted into a date object. The most interesting part of the new Date('') function is that it can convert a date passed in a string format as an argument into a date format. The new Date() will return a date object as depicted by the date string passed as an argument. new Date() will return the current system date and time, including the timezone information in the local system time, if no parameter is passed to the new Date() function. new Date() takes arguments in various forms described below but returns a date object.

The most commonly used way to convert a string to date is with the new Date() function. Attempt to de reference a null object Salesforce Exception
