I ran into some old code that adds 7 days to a date and spits it out in a DateFormat().
Normally you’d do this:
dateFormat( dateAdd( 'd', 7, now() ), 'mm/dd/yyyy' );
But the code I ran into doesn’t use the dateAdd() method. It just simply adds days.
dateFormat( now() + 7, 'mm/dd/yyyy' );
Though I can’t find this shortcut documented anywhere it seems to be working well with at least ColdFusion v8 and v9.
