Calculating a Future Date

If you are creating a VBA 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. There are many different intervals you can specify:

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:

dFutureDate = DateAdd("d", 90, Date)

When executed, dFutureDate contains the date that is 90 days after today.
