Explain more clearly. What's the language?

A date cannot be "remaining". Remaining can be the time span, for example from the current time to some stated date such as deadline. Here is how can it look in C#:

C#

int RemainingDays(System.DateTime setTime) { //setTime is from your data base
    System.TimeSpan span = System.DateTime.Now - setTime;
    return span.Days; //can be negative if overdue
}

If you need to get time from the date represented as string, read about the following methods:

System.DateTime.Parse(string);
System.DateTime.Parse(String, IFormatProvider, DateTimeStyles);
System.DateTime.ParseExact(String, String, IFormatProvider); (you can use System.Globalization.CultureInfo as IFormatProvider);
System.DateTime.ParseExact(String, String, IFormatProvider, DateTimeStyles);
System.DateTime.ParseExact(String, String[], IFormatProvider, DateTimeStyles)
