Only the ISO 8601 format ( YYYY-MM-DDTHH:mm:ss.sssZ) is explicitly specified to be supported. The new Date() constructor takes the date string as an argument and creates the new date object. Note: The date string should be in ISO format (YYYY-MM-DD or MM/DD/YYYY or YYYY-MM-DDTHH:MM:SSZ) Using new Date() constructor. If your format is incompatible (I think it is), you have to parse the string yourself (should be easy with regular expressions) and create a new Date object with explicit values for year, month, date, hour, minute and second. The Date.parse () method parses a string representation of a date, and returns the number of milliseconds since January 1, 1970, 00:00:00 UTC or NaN if the string is unrecognized or, in some cases, contains illegal date values (e.g. Now, we need to convert the above date string to an actual date object with JavaScript. If you don't know the exact format of an input string, but know it could be one of many, you can use an array of formats. Use new Date(dateString) if your string is compatible with Date.parse(). dayjs( '', 'YYYY-MM-DD').isValid() // trueĭayjs( '', 'YYYY-MM-DD', true).isValid() // falseĭayjs( '', 'YYYY-MM-DD', 'es', true).isValid() // false Just concatenate your date string (using ISO format) with T00:00:00 in the end and use the JavaScript Date() constructor, like the example below. Strict parsing requires that the format and input match exactly, including delimiters. You may specify a boolean for the last argument to use strict parsing. Pass the locale key as the third parameter to parse locale-aware date time string.
You can learn more about toISOString in documentation.If you know the format of an input string, you can use that to parse a date. You can learn more about toDateString in documentation. Use the toUTCString() method instead toISOString Returns the date as a string, using the ISO standard toJSON Returns the date as a string, formatted as a JSON date toLocaleDateString Returns the date portion of a Date object as a string, using locale conventions toLocaleTimeString Returns the time portion of a Date object as a string, using locale conventions toLocaleString Converts a Date object to a string, using locale conventions toString Converts a Date object to a string toTimeString Converts the time portion of a Date object to a string toUTCString() Converts a Date object to a string, according to universal time toDateString() ToDateString Converts the date portion of a Date object into a readable string toGMTString Deprecated. const dateString '' var mydate new Date (dateString + 'T00:00:00') console.log (mydate. The Date () constructor creates and returns a new Date object. That's the best and simpler solution in my view: Just concatenate your date string (using ISO format) with 'T00:00:00' in the end and use the JavaScript Date () constructor, like the example below. Pass the year, month minus 1 and the day to the Date () constructor. So you should be able to do: var date new Date (record.LastModifiedDate) console.log (date. To convert a dd/mm/yyyy string to a date: Split the string on each forward slash to get the day, month and year. The record datetime field should be the seconds since the epoc. Javascript however provides multiple functions to present date and time in human readable form. method to convert date time to date format in javascript.
Unlike other languages, JavaScript doesn't have equivalent for function strftime.
