Julian Date

Calculates Julian Date.
The example below uses Today, but any valid date object will work.
Sub Initialize
Dim dt As New notesdatetime(Today)
Dim x As Long, y As Long
'Get the correct julian day
x& = Datenumber(Year(dt.localtime),Month(dt.Localtime),Day(dt.LocalTime))
y& = Datenumber(Year(dt.localtime),1,1)
tdif = Trim(Str((x& - y&) + 1))
threedigit = Right("000",3-Len(tdif)) + tdif ' Pad julian date with 0's
Msgbox "Today's julian date is: " + threedigit
End Sub
