Script version to find last date of month

This script finds the last date of the month whether or not the month has 28, 29, 30 or 31 days. The field that holds the date is from the current document and is called "BeginPer." The NotesDateTime variable "endday" is what holds the value of the last date of month. 
If Month(uidoc.FieldGetText("BeginPer")) <> 12 Then
  nam_dt = (Month(uidoc.FieldGetText("BeginPer"))+1) & "/01/" & Year(uidoc.FieldGetText("BeginPer"))
Else 
  nam_dt = "01/01/" & (Year(uidoc.FieldGetText("BeginPer")) + 1)               
End If          
Set endday = New NotesDateTime(nam_dt)
Call endday.AdjustDay(-1)
