HOW TO add weeks to Date or DateTime

The Date and DateTime structures have the following methods:
AddYears(), AddMonths(), AddDays() but NOT AddWeeks() so you could use AddDays() to add the number of days of the week for each week or simply Add() to add TimeSpan, these aren’t professional solutions.

Use AddWeeks() method of Calendar class:

[sourcecode lang=”vb”]
Imports System.Globalization

Dim cal As New Calendar

Dim newDate as Date = cal.AddWeeks(myDateTime, 1).Date
Dim newDateTime as DateTime = cal.AddWeeks(myDateTime, 1)
[/sourcecode]

Also, you can use specific calendar changing Calendar class with others: GregorianCalendar, JapaneseCalendar, etc.
To read the complete list System.Globalization Namespace
