The VBScript “DateAdd” allows you to add days to a date. The Syntax is:

```
DateAdd(interval,number,date)
```

For example, to add 4 days, you use:

```
DateAdd(d,4,Now())
```

The issue is, this doesn’t include weekends. However I fell across this solution thanks to Sholsinger:

```
Function BusinessDayAdd(delta, dt)
dim weeks, days, day
weeks = Fix(delta/5)
days = delta Mod 5
day = DatePart("w",dt)
If (day = 7) And days > -1 Then
If days = 0 Then
days = days - 2
day = day + 2
End If
days = days + 1
day = day - 7
End If
If day = 1 And days < 1 Then
If days = 0 Then
days = days + 2
day = day - 2
End If
days = days - 1
day = day + 6
End If
If day + days > 6 Then days = days + 2
If day + days < 2 Then days = days - 2
BusinessDayAdd = DateAdd("d", (weeks * 7 + days), dt)
End Function
```

To use this function, call it as follows:

```
BusinessDayAdd(4,Now())
```
