Hi Dori,

It's very hard to solve something like this without a diagram.  Here's
the diagram I would draw:

 +----------+----------+---------+-----+--------+---------+
 |Day before|Day before|Yesterday|Today|Tomorrow|Day after|
 |day before|yesterday |         |     |        |tomorrow | 
 |yesterday |          |         |     |        |         |
 +----------+----------+---------+-----+--------+---------+
      ^
      |
      |________ 5 days before the day after tomorrow


Does this help?
