It returns the number of milliseconds that have elapsed since January 1 at 0:00 UTC. Similar to the Date.parse() constructor, the static function Date.UTC() also accepts parameters. The example above demonstrates how to use the static function parse of the Date constructor to transform a date from a string to a Date object. This function returns NaN if the parameters are not provided in the proper format. The text representation of the date is parsed to produce a date, which is returned together with an integer containing just the milliseconds from January 1st, 1970, 00:00:00 UTC. The parse method of the date constructor also requires a string parameter that provides a date in the ISO 8601 calendar date extended format. It parses a date represented as a string and returns the duration in milliseconds, disregarding leap seconds. A static method called parse exists here. Date.parse() constructorĪnother way to convert a date from string to Date format is provided by the date constructor. The illustration demonstrates how to use the constructor of the Date class to transform a date from a string to a Date object. Sat 00:00:00 GMT+0100 (West Africa Standard Time) Output: Sat 00:00:00 GMT+0100 (West Africa Standard Time) This function returns "Invalid Date" if the parameters are not in the correct format. More precisely, the return value contains a number that is just the number of milliseconds from January 1, 1970, 00:00:00 UTC, and the date that was obtained by parsing the supplied string representation of the date. The date format is used for the return type. Let's take a quick look at this element.Ī string containing a date in the ISO 8601 calendar date extended format should be provided as the first argument to the constructor of the Date class. Additionally, you can change a date value from a string data type to a Date data type with the constructor. This function can be used to retrieve the local system's current date and time. JavaScript has a constructor called the Date constructor. Let’s explore these methods in some detail.
