If you are creating a macro to do some processing on a document, you may have a need to calculate a date at some point in the future. Using the VBA DateAdd function, this is quite easy. The function has the following syntax:
DateAdd(interval, number, startdate)
The original date that you begin with (typically today's date) is specified by the startdate argument. The interval argument indicates what you want to add to the startdate. For instance, if you want to add days, then interval would be the letter d. (This interval needs to be enclosed within quotes.) There are many different intervals you can specify:
| Interval | Meaning | |
|---|---|---|
| d | Day | |
| ww | Week | |
| m | Month | |
| q | Quarter | |
| yyyy | Year | |
| y | Day of year | |
| w | Weekday | |
| h | Hour | |
| n | Minute | |
| s | Second |
Finally, the number argument specifies how many intervals you want to add to the date.
As an example, let's suppose you wanted to know the date that was 90 days in the future. You could use the following:

How do you insert this macro into a Word document? I have been using a Date Picker Context Control box, for a current date, but I need to add a block for a future date. Can you please help me?
Thanks,

Private Sub Document_Open()
Dim myDate As Date
Dim myRng As Range
'Set the starting date with the value of a field
Set myRng = ActiveDocument.Fields(1).Result
myDate = myRng
myRng = DateAdd("d", 1, Date)
End Sub
