Help needed on Date formulas

[shminas]

Hi,
I need to keep track of weekly bug counts on a periodic basis.Her
is an example

Date logged P1 bugs P2 bugs Week Logged(Sunday)
[To be calculate
using formula]
01/02/2006 2 3 01/0/12006
01/05/2006 3 5 01/01/2006
01/10/2006 5 5 01/10/2006

In Excel,I would like to find out using formulas, the exact bug count
for each week,by manipulating the date logged.Irrespective of any dat
it was logged,there should be a column which contains the formula,t
find the week in which the bug was logged.Is it possible in Excel ?

Please help.

This formula always returns the previous Sunday (or on a Sunday that
day's date) for a date in A1

=A1+1-WEEKDAY(A1)
