JavaScript Date.UTC() Method

The Date.UTC method returns a number representing the number of milliseconds for the given date since January 1, 1970, 00:00:00, UTC.

It takes comma-delimited date and time parameters.

Note: If a parameter is outside of the expected range, the UTC() method updates the other parameters to accommodate the value. For example, if 13 is used for month, the year will be incremented by 1 (year + 1) and 1 will be used for the month.
