# Date adjustment rule (e.g. availability date)

First choose Export -> Edit (see previous example)&#x20;

Next, go to Rules -> New Rule and select Edit Element

![](/files/LpvBHU4DptSI4v79WQ0I)

Select the element in which you want to write the resulting date&#x20;

Select the "Date" content type&#x20;

Now you need to select "Replace content"&#x20;

Type "today" (as today to which the days will be added)&#x20;

To add a day to the date, use the format "+ XXX days" where XXX can be the exact number of days, eg "10". The original value of 10 becomes the date today + 10 days.&#x20;

The second option is to use a variable that have a number of days
