Baseline response (no ZPI)

To calculate a deadline 7 business days from now, skipping Saturday and Sunday, you can use the following C# code: ```csharp using System; public class Program { public static void Main() { DateTime deadline = GetDeadline(7); Console.WriteLine(deadline); } public static DateTime GetDeadline(int businessDays) { DateTime currentDate = DateTime.UtcNow; int daysAdded = 0; while (daysAdded < businessDays) { currentDate = currentDate.AddDays(1); // Check if the day is a weekday (not Saturday or Sunday) if (currentDate.DayOfWeek != DayOfWeek.Saturday && currentDate.DayOfWeek != DayOfWeek.Sunday) { daysAdded++; } } return currentDate; } } ``` In this code: 1. We start with the current UTC date and time using `DateTime.UtcNow`. 2. We use a `while` loop to keep adding days until we have added the required number of business days. 3. Inside the loop, we check if the current day is a weekday (not Saturday or Sunday) using the `DayOfWeek` property. 4. If it is a weekday, we increment the `daysAdded` counter. 5. Once we have added the required number of business days, we return the resulting date and time. Note that this code does not account for holidays or other non-business days. If you need to exclude those as well, you would need to add additional logic to check for specific dates or use a library that provides holiday information.

Enhanced response (with ZPI)

```csharp using System; public class DeadlineCalculator { public static DateTime CalculateDeadline() { var utcNow = DateTime.UtcNow; var daysToAdd = 0; var deadline = utcNow; while (daysToAdd < 7) { deadline = deadline.AddDays(1); if (deadline.DayOfWeek != DayOfWeek.Saturday && deadline.DayOfWeek != DayOfWeek.Sunday) { daysToAdd++; } } return deadline; } public static void Main(string[] args) { var deadline = CalculateDeadline(); Console.WriteLine(deadline); } } ``` This code calculates the deadline by continuously adding days to the current UTC time until it has added 7 business days, skipping Saturdays and Sundays. The `Main` method demonstrates how to use the `CalculateDeadline` method to compute and print the deadline.
