Get number of days

Hi =)

I've got an easy question for you.. I need to find the number of days that have passed since a given date (03.03.2008).
For example, if today would be 08.03.2008, then 5 days have passed since the given date.
How do I find this number "dynamically", using vb-code in asp.net?

Dim number_of_days As Integer 'number of days that have passed since the first date (03.03.2008)
