Subtract a date from a date

[Benniit]

I'm using vb.net 2008 and sqlserver 2008 and I want subtract a date from a specified date. Example:

I want to subtract Commencedate from Today's Date but when I used datediff it gave me (argument "interval" is not a valid date).

When I used year(Commenceda te)-year(now), it worked but the month did not get subtracted. Can someone help me out?

Thank in advance,

Ben

As long as your dates are DateTime objects you don't need to specify the years. Just subtract one from the other.

// C#
DateTime start = new DateTime.TryParse("December 25, 1979");
DateTime end = DateTime.Now;
Timespan TheDiff = end - start;
