In the last post, we added some math formulas to numeric fields, but pointed out that this does not work with traditional Date fields. So what are we doing here? There is a different method that you can use that will allow you to do this.
Instead of using a Date field, we are going to use a DIESEL expression. If that sounds strange, don't fear. I will not cover intricate details regarding DIESEL functions and you will not need it for this tutorial.
