Parsing a date will give us the time in milliseconds. Date.parse() is used to parse a date. This method actually returns a number of milliseconds between the provided date and January 1, 1970. It is programmed in that way by the developers to get time in milliseconds from January 1, 1970 to the date provided.

In the following example, using Date.parse() a number of milliseconds were calculated between July 14, 2019 and January 1, 1970.
