ADD / SUBTRACT FROM DATES

It is often necessary to add or subtract values from dates. Here are a few examples of how to do it:

Adding to Dates

<% Response.Write DateAdd ("m", 1, #4/17/01#) %>

This adds one month to the date 4/17/01: 17/05/2001

<% Response.Write DateAdd ("d", 1, Date) %>

This displays tomorrows date like this: 01/12/2011

Subtracting from Dates

<% Response.Write DateAdd ("d", -1, Date) %>

This displays yesterdays date like this: 29/11/2011
