The format for Date() constructor is like Date(month, date, year, time). By following this format some values is given in the below program and corresponding string is produced as output. Time format should be like (number:number:number). If time do not lie in this format, it gives output as Invalid date.

Important Points
Months, Date, hour, minute, second and millisecond should must be in their respective range of 0 to 11 for months, 1 to 31 for date, 0 to 23 for hours, 0 to 59 for minute, 0 to 59 second, 0 to 999 for milliseconds otherwise toDateString() function return Invalid Date.
Let’s see JavaScript code on this out of range topic:
Example 1 : Here date given as of 45 which is out of range of date that is why below code gives output as null.
