The Date type in ECMAScript is built on the Java.unile.Date class in early Java. This date type uses the number of milliseconds since UTC (Coordinated Universal time, international coordination times) to start at midnight January 1, 1970 to save dates.

In this data storage format, date types can be saved in exactly 285,616 years before or after January 1, 1970

Date.parse (String)

Accept a string parameter that represents the date, and then try to return the number of milliseconds based on that string, and then return NaN

DATE.UTC (year, month[, day, Hour, Min, second, millisecond])

The number of milliseconds to return the corresponding date according to the parameter, only the first two parameters are required, omitting the other parameters are all assumed to be 0

Date.now ()
