Day: (Required) An integer value representing the day of the month (1 to 31, depending on the month).

Example: Create a Specific Date

Use Cases:

Creating Specific Dates: Easily create dates for calculations, comparisons, and other date-related operations.
Date Calculations: Perform date arithmetic, such as adding or subtracting years, months, or days to a specific date.
Generating Reports: Create reports with dynamic dates, such as reports for the current month or the last quarter.

Key Considerations:

Valid Date Ranges: Ensure that the provided year, month, and day values create a valid date. For example, February cannot have more than 29 days in most years.
Error Handling: Consider using error handling (e.g., On Error Resume Next) to gracefully handle invalid date combinations.
