Update for SharePoint 2013: although MSDN lists Offset as an attribute for Today element (https://msdn.microsoft.com/en-us/library/office/ms460496.aspx), when customizing the CAML on a list view in SharePoint Designer 2013 I tried the Offset attribute but it didn't work. I used the "OffsetDays""OffsetDays
" attribute (not documented in MSDN) and the query returned the desired output (items with date field up to 5 days from the current date).
