If x is any Date whose milliseconds amount is zero, then x.valueOf() should be equal to any of the following: Date.parse(x.toString()), Date.parse(x.toUTCString()), Date.parse(x.toISOString()). This means the formats produced by {{jsxref(\"Date/toString\", \"toString()\")}} and {{jsxref(\"Date/toUTCString\", \"toUTCString()\")}} should be supported too. The spec does _not_ require support for the format produced by {{jsxref(\"Date/toLocaleString\", \"toLocaleString()\")}}. However, major engines all try to support toLocaleString(\"en-US\") format.\n\nOther formats are implementation-defined and may not work across all browsers. A library can help if many different formats are to be accommodated. In fact, the unreliability of Date.parse() is one of the motivations for the {{jsxref(\"Temporal\")}} API to be introduced.\n\nBecause parse() is a static method of Date, you always use it as Date.parse(), rather than as a method of a Date object you created.\n\nAttribution: Adapted from MDN Web Docs under CC-BY-SA-2.5.
