Datetime interval checker - ASP.NET, VB.NET
Its simple snap of code that i think that could be useful. Hope it will help you someway.
Dim upperDate As Date = "#30/6/" & DateTime.Now.Year & "#"
Dim lowerDate As Date = "#1/6/" & DateTime.Now.Year & "#"
If Not (Date.Compare(Date.Today, upperDate) < 0 And Date.Compare(Date.Today, lowerDate) > 0) = True Then
Response.Redirect(http://www.snb-bg.com) ' Do something if not between 1.6.2009 and 30.6.2009
End If
Cheers
