Program 2: The date of the month must lie between 1 to 31 because a month cannot have more than 31 days. That is why it returns NaN i.e, not a number because the date for the month does not exist. Hence, Year will not exist when the date of the month is set as 45 or any number which does not lie between 1 to 31.
