You say you want to calculate 4 week periods. I'm not sure what that
means, you just want a list?

If you put the start date of period 1 in B2, i.e. 29-May-2009 then C2
will calculate the end date with the formula

=B2+27

then in B3 you can use the formula

=B2+28

and then copy that formula across to C3 and down both columns as far as
you need. Format all cells in the required date format
