You want to calculate period between tow date, like, two different fields, right?
In this case you better do the math in c# (in Row_Insterting / Row_Updating).

The period is expressed in what? Days, Hours, Minutes?

Days , but this period will be between two fields , one set as current date and the other is normal selected date/

DateTime dtStartDate = Convert.ToDateTime(rsnew["event_start_date"]);
DateTime dtEndDate = Convert.ToDateTime(rsnew["event_end_date"]);

TimeSpan tsDiffOfDates = dtEndDate.Subtract(dtStartDate);

int iDaysBetweenDates = diffOfDates.Days;
...

Go to learn.microsoft.com and look for TimeSpan Struct for other examples ...

If you want to calculate days between different dates in client codes, you can refer to the examples in:
