I have a table of week end dates, "most" of them are Saturday, so I could
just say (date - 6),

what SQL do I use to return the previous closest Sunday?

(bonus points to help me when I need to start on "01-01-xxxx", not Sunday)

this (almost) works, except for beginning and end of year:

SELECT idate.idate(enddt) as end_date, (idate.idate(enddt)-6 days) as
start_date
from week_table;
