Hello,

The first chart below shows dates and clock in time and clock out times
(formatted as time).

The next chart below shows where I would like the total hours to appear.
However the chart below shows week ending dates. I need a formula that will
calculate not only the date in the first column but also the previous 6 days
(before the date).

Note: The week ending date does change week to week so the formula would
need to reference a cell number, not a specific date.
