What is a week?

[Marcin Borkowski]

Hi fellow Orgers,

I'm trying to wrap my head around the notion of the week, for the
purpose of using weekly clock tables.

Assume it's Sunday.  I create a clock table with :wstart 0 and
thisweek - and apparently my clock table starts 7 days ago.

Now it's Monday.  I create a clock table with :wstart 1 and thisweek -
and my clock table starts today.

What is the logic behind it?

Help!
