Elliot Levine in 8-Dec-2000 at submitted this as a
formula. I needed it in LotusScript form and came up with this.
' Calculate Friday week ending date for given date. Dim dTime As New NotesDateTime (DateWorked) Dim adjust_days As Integer Dim this_weekday As Integer Dim weekday_difference As Integer Const FRIDAY_WEEKDAY = 6 this_weekday% = Weekday (dTime.LSLocalTime) weekday_difference% = FRIDAY_WEEKDAY - this_weekday% If (weekday_difference% = -1) Then ' Saturday shifts into next week. adjust_days% = FRIDAY_WEEKDAY Else ' Adjust other days one week backwards, less their distance from Friday. adjust_days% = - (weekday_difference%) End If Call dTime.AdjustDay (adjust_days%)
